For six adults spending several weeks in Seoul, the two strongest single-unit options are Orakai Insadong Suites' Four Bedroom suite (four bedrooms, two bathrooms, a full kitchen and an in-room washer-dryer) and the Penthouse at Long Weekend Haus DDP near Dongdaemun Design Plaza (three bedrooms, four double beds, two bathrooms, a kitchen and an in-unit washer-dryer, for up to eight adults). Fraser Place Central's three-bedroom apartment is a third choice once six-adult occupancy is confirmed in writing, while Somerset Palace Seoul works only as two units and a registered homestay is the fallback. All five are ranked on whether six adults fit within the published occupancy, how many bedrooms and bathrooms they share, whether laundry and cooking happen inside the unit, and how certain the booking is after Airbnb's 2026 licence enforcement in Korea.
A month in Seoul with six adults used to send most groups straight to a large Airbnb house. That default has become less reliable. According to The Korea Times, Airbnb said hosts who had not submitted business registration information by October 16, 2025 would not be allowed to accept reservations for stays after January 1, 2026. Operator-run apartment hotels and serviced residences are booked directly with a named business, which makes them the steadier starting point for a six-person, multi-week stay.
Quick Answer
- Most private sleeping space for six: Orakai Insadong Suites, Four Bedroom. Four separate bedrooms, a king bed plus four single beds, two bathrooms.
- Most headroom and the best fit for an adults-only group based near DDP: Long Weekend Haus DDP, Penthouse. Rated for up to eight adults, so six people are well inside the limit, with three bedrooms and two bathrooms. Its Maru Suite (two bedrooms, three double beds, up to six) suits groups comfortable sharing beds in pairs.
- Full-service residence with three bathrooms: Fraser Place Central, three-bedroom. Check six-adult occupancy before paying.
- When no single unit is free: two two-bedroom units at Somerset Palace Seoul.
- When you want a house: a homestay listing that displays a valid Korean registration number.
Check exact dates for every option. None of the prices, monthly discounts or availability are fixed, and month-long rates are rarely published.
How the five picks were ranked
Each property was checked against the official page of the operator wherever one exists, with booking-site listings used only to fill in bed counts or occupancy the operator does not publish. The criteria, in order of weight:
- Six adults within the published occupancy. A unit marketed as "sleeps 6" that charges a seventh-bed fee or reaches six only with sofa beds ranks lower than one built for six or more.
- Bedrooms and bed sharing. Six adults rarely want three couples' worth of shared beds for 30 nights. More bedrooms and more separate beds score higher.
- Bathrooms. For six people over a month, the second bathroom matters more than almost any amenity.
- In-unit kitchen and laundry. A month of restaurant meals and laundromat trips adds up. A kitchen or kitchenette inside the unit is required for a top-three placement, and a confirmed in-unit washer-dryer weighs heavily.
- Booking certainty. A booking made directly with a named operator on its own site, or a homestay showing a government registration number, ranks above an anonymous listing.
Location is a tiebreaker only. All four apartment hotels below sit in central Seoul (Jongno-gu or Jung-gu) with subway access.

| Rank | Property and unit | Bedrooms and beds | Bathrooms | Kitchen and laundry | Six-adult fit | Area |
|---|---|---|---|---|---|---|
| 1 | Orakai Insadong Suites, Four Bedroom | 4 bedrooms; 1 king + 4 single | 2 | Full kitchen, in-room washer-dryer | Listed as sleeping 6; confirm extra-person rules | Insadong, Jongno-gu |
| 2 | Long Weekend Haus DDP, Penthouse (or Maru Suite) | 3 bedrooms, 4 double beds (Maru: 2 bedrooms, 3 double beds) | 2 (Maru: confirm) | Kitchen, in-unit washer-dryer | Penthouse up to 8; Maru up to 6 | Ssangnim-dong near DDP, Jung-gu |

1. Orakai Insadong Suites, Four Bedroom
Best for: Six adults who each want as close to their own bed as possible, including multi-generational adult families.
What to know: The official Orakai Four Bedroom page describes four separate bedrooms, a living room, a dining area, a fully equipped kitchen, two bathrooms and a 135-165 m² floor area, with a king bed plus four singles. The kitchen lists a microwave, oven, refrigerator and dishwasher, and the room includes an in-room washer-dryer. A trivago listing shows the four-bedroom apartment as sleeping six and notes an extra-person charge for guests over age six.
Strength: Four bedrooms and five beds for six adults means only one pair shares a bed, the least bed sharing among the picks with published bed counts.
Limitation: Six is the listed capacity, so there is no margin. A seventh traveller or a visiting friend staying over will trigger extra-person rules.
Evidence: Operator room page for layout, beds, kitchen and laundry; booking listing for the six-person capacity.
For a month, ask Orakai for a long-stay quote on the exact four-bedroom category. The building also sells two- and three-bedroom layouts, and the kitchen and bed details above apply to the four-bedroom unit you book.
2. Long Weekend Haus DDP, Penthouse or Maru Suite
Best for: Adult friend groups or adult families who want one shared base near Dongdaemun Design Plaza with room to spare, plus a kitchen and a washer-dryer for a long stay.
What to know: Long Weekend Haus DDP is an apartment-hotel-style boutique stay in Ssangnim-dong, Jung-gu, booked through the Long Weekend Haus DDP official room page. The page lists suites by room type. The Penthouse has three bedrooms and two bathrooms for up to eight adults. The Maru Suite has two bedrooms for up to six. Both include a kitchen and an in-unit washer-dryer. Long Weekend Haus's own Dongdaemun stay guide gives the bed layout: four double beds in the Penthouse and three in the Maru Suite. The same guide gives a 15:00 check-in and 11:00 check-out, with arrival through a self check-in kiosk.
Strength: The Penthouse is the only pick here rated above six people. Six adults sit two below the limit, with two bathrooms and three bedrooms. For a group that can share beds in pairs, the Maru Suite offers six-person capacity in one unit.
Limitation: Bed sharing is built in. Four doubles for six people means at least two pairs share, and the Maru Suite's three doubles mean everyone shares. The Maru Suite's bathroom count is not published alongside the Penthouse figure, so confirm it. The official page shows a 19-and-over notice, so any group that includes a minor should confirm the age policy with the property before booking. Long-stay rates and mid-stay housekeeping are not published.
Evidence: Operator room page for unit types, capacity, bedrooms, bathrooms, kitchen, laundry and self check-in; operator's published guide for bed counts and check-in times.
The smallest suite, the Dining Suite (two bedrooms, up to four guests), does not fit six. Search with six adults and your exact dates so only eligible suites appear.
3. Fraser Place Central, three-bedroom
Best for: Groups who want a staffed serviced residence with three bedrooms and are willing to secure written confirmation of six-adult occupancy.
What to know: Frasers Hospitality describes Fraser Place Central as offering short- and long-term stays for individuals and families, with 269 furnished apartments ranging from studios to three-bedroom suites in the Gangbuk area. A SilverDoor listing shows the three-bedroom apartment at roughly 149 m² with three bathrooms and kitchen facilities including a hob, microwave, fridge and rice cooker. A CityzenBooking listing, however, shows the three-bedroom apartment for five persons.
Strength: Three bathrooms in the reseller listing, the most of any apartment hotel here, which matters for six people sharing morning routines over a month.
Limitation: The published sources disagree on whether six adults are allowed. Treat five as the safe assumption until the property confirms six in writing, including any extra-bed fee.
Evidence: Operator page for unit range and long-stay positioning; reseller listings for bathrooms, kitchen and occupancy.
4. Somerset Palace Seoul, two units
Best for: Groups whose dates are blocked at the single-unit options, or six adults who would prefer two smaller households under one roof.
What to know: The Ascott's Somerset Palace Seoul page states a base occupancy of three persons for Two-Bedroom Executive types and four for the Penthouse, with an Executive Suite card showing a maximum of four and the Penthouse Premier a maximum of five once chargeable extra guests are added. On Expedia, the two-bedroom Executive Room lists a kitchen, a washing machine and about 80 m².
Strength: Two units give six adults two kitchens, two washers and at least two bathrooms, which can work better over 30 nights than one crowded apartment.
Limitation: No single unit holds six, so the group pays for two apartments, and nothing guarantees they sit side by side. Ask for nearby units when booking.
Evidence: Operator page for occupancy limits; booking listing for unit kitchen and laundry.
Whether two units beat one suite on cost depends on the dates. Long Weekend Haus's suite-versus-rooms cost guide walks through comparing all-in totals for the same nights.
5. A registered homestay house
Best for: Groups who want a private house or villa and will check the licence themselves.
What to know: Airbnb's Korea hosting page says listings created before October 2, 2024 had to submit an accommodation licence by October 16, 2025, and listings that did not submit cannot accept bookings. Ur Korean BFF's 2026 explainer says a legal listing is registered as a Foreign Tourist Urban Homestay Business and advises looking for the registration number in the listing or host profile. The same explainer says officetels cannot be legally hosted short-term.
Strength: A registered house can offer more bedrooms per person than any apartment hotel.
Limitation: There is no front desk or operator standard, and verification falls on you. Ur Korean BFF notes that booking an unregistered stay will not get the guest fined, but it can lead to a cancellation with little warning.
Evidence: Platform policy and a current traveller explainer.
Decision guide
Every adult needs a bed, and six is the final headcount. Book the Orakai Four Bedroom.
The group is all adults, may grow by one or two, or the plan centres on Dongdaemun and Jung-gu. Book the Long Weekend Haus DDP Penthouse. If everyone is comfortable sharing doubles in pairs, compare the Maru Suite for the same dates.
You want a staffed residence and three bathrooms. Ask Fraser Place Central to confirm six adults for the three-bedroom unit in writing before you pay.
Single units are sold out. Book two units at Somerset Palace Seoul and request proximity.
You want a house. Only book a homestay showing a registration number, and avoid officetel listings.
Before confirming any month-long booking, get these answers in writing: the total for all nights including taxes and service fees, the cancellation and early-departure terms, whether housekeeping or linen changes happen mid-stay, and whether detergent and kitchen basics are supplied. Then enter six adults and the exact dates on each official site so only eligible units appear.
FAQ
Do apartment hotels in Seoul publish monthly rates?
None of the four apartment hotels above publishes a fixed 30-night price on the pages reviewed. Request a long-stay quote for the exact unit and dates, then compare the all-in total against 30 nights at the nightly rate.
Can a homestay listing without a registration number still be booked?
Under Airbnb's policy, listings that missed the licence submission cannot accept bookings, so an unregistered listing still taking reservations is a warning sign. If one appears on another platform, ask the host for the registration number before paying.
Are children allowed at these properties?
Policies differ. Long Weekend Haus DDP's official page shows a 19-and-over notice, so confirm directly if anyone in the group is under 19. Orakai listings note an extra-person charge for guests over age six, and Somerset Palace charges for guests above each unit's base occupancy.
Is it better to book one unit or two for six adults?
One unit keeps the group together and usually means one kitchen and one laundry bill. Two units buy privacy and a second bathroom. Compare the total for both on the same dates before deciding.
