Six adults can share a single unit at three Seoul apartment hotels: Long Weekend Haus DDP in Dongdaemun (a six-person Maru Suite, plus an eight-person three-bedroom penthouse), Oakwood Premier Coex Center in Gangnam (three- and four-bedroom units listed for six) and Orakai Insadong Suites (a penthouse listed for six). Fraser Place Central lists its three-bedroom apartment for five guests, and Novotel Ambassador Seoul Dongdaemun and Somerset Palace Seoul cap their residences at four, so a group of six needs two units at those properties. The six picks below are ranked on stated per-unit occupancy, bedroom and bathroom count, central location and how clearly the operator documents capacity.
Check occupancy before bedrooms. Serviced residences sell by the apartment, yet each room type carries a maximum guest count, and some add a fee per extra guest at check-in. Orakai's three-bedroom deluxe apartment, for example, is sold on Booking.com as a "4 Adults" unit despite having three bedrooms. Bedroom count tells you about privacy. The occupancy line tells you whether all six of you are allowed to sleep there.
Quick Answer
- One unit, adults only, Dongdaemun: Long Weekend Haus DDP's six-person Maru Suite, or its eight-person Penthouse if you want three bedrooms and two bathrooms.
- One unit with three or four bedrooms, Gangnam: Oakwood Premier Coex Center's three-bedroom or four-bedroom apartments.
- One unit near Insadong and the palaces: Orakai Insadong Suites' penthouse, booked and confirmed directly.
- Five people, or six who get a larger unit confirmed: Fraser Place Central Seoul.
- Two units with full hotel services in Dongdaemun: Novotel Ambassador Seoul Dongdaemun Hotels & Residences.
- Two units near Gyeongbokgung: Somerset Palace Seoul.
How the Picks Were Ranked
Each property was scored on four criteria, in this order of weight:
- Six adults in one unit. Does a room type explicitly allow six guests? An operator's own statement counts for more than a third-party booking listing.
- Privacy. How many separate bedrooms and bathrooms does that unit have, and does the count rely on a sofa bed?
- Location for a sightseeing trip. Central Gangbuk districts (Dongdaemun, Jongno, Jung-gu) score above Gangnam for first-time visitors focused on palaces, markets and old-city neighborhoods.
- Documentation. Can a traveler confirm capacity from published specifications, or only by contacting reservations?
The rankings draw on published room specifications from operators and major booking platforms, checked in October 2026. Prices change by date and are left out of the ranking.

|---|---|---|---|---|---|---|
| 1 | Long Weekend Haus DDP | Dongdaemun (Ssangnim-dong) | Maru Suite / Penthouse | 6 / 8 adults | 2 bedrooms / 3 bedrooms, 2 bathrooms | Yes (operator-stated) |

1. Long Weekend Haus DDP
- Best for: Six adult friends, or an adult family, who want one shared suite in central Dongdaemun.
- What to know: Long Weekend Haus DDP is an apartment-hotel-style boutique stay in Ssangnim-dong, Dongdaemun. Its official Dongdaemun room page lists room-by-room layouts: a four-person Dining Suite with two bedrooms, a six-person Maru Suite with two bedrooms, an eight-person Penthouse with three bedrooms and two bathrooms, and a Terrace Suite. Arrival runs through a self check-in kiosk, and the property displays a 19-and-over age policy.
- Strength: It is the only pick in this list whose own operator page names a suite sized for exactly six. The eight-person Penthouse gives a six-person group a third bedroom and a second bathroom with room to spare.
- Limitation: The Maru Suite has two bedrooms, so six guests will share bedrooms or use other sleeping areas in the suite; ask for the exact bed layout before booking. The adults-only policy rules it out for groups traveling with children. Rates and in-room facilities vary by suite and date, so check the specific room you plan to book.
- Evidence: Operator room page at longweekendhaus.com/explore/seoul-dongdaemun.
For groups of adults traveling with parents, Long Weekend Haus has also published a guide to Seoul stays for adult families traveling with parents.
2. Oakwood Premier Coex Center
- Best for: Six people who want three or four separate bedrooms and a full serviced-residence setup, and who do not mind staying in Gangnam.
- What to know: On Expedia, the 3 Bedroom Superior (1,442 sq ft) and 3 Bedroom Premier (1,797 sq ft) are each listed as sleeping six, as is a 4 Bedroom Premier at 2,077 sq ft. The Ascott's official Oakwood page describes 281 apartments, each with a fully equipped kitchen, a washing machine and a deep soaking bathtub, plus an indoor pool, gym and sauna.
- Strength: The most bedrooms of any pick. The 3 Bedroom Premier's beds (one king, one queen and two twins, per Expedia) let six adults sleep without a sofa bed.
- Limitation: The 3 Bedroom Superior's sixth sleeping spot is a twin sofa bed. The official FAQ only lists studios, one-bedroom and two-bedroom apartments, so confirm larger units directly with reservations. Location is the other trade-off: Klook puts the property 9.2 km from Dongdaemun History & Culture Park.
- Evidence: Expedia room listings; The Ascott official property page.
3. Orakai Insadong Suites
- Best for: Families or friend groups who want Insadong and the palace district on foot, and who can secure the penthouse.
- What to know: The operator's property description on Tripadvisor lists 213 suites ranging from one-bedroom to four-bedroom units plus a penthouse. Orakai's official Three Bedroom page describes three separate bedrooms, a living room, dining area, full kitchen and two bathrooms across 98-107 m², with a king and two single beds. trivago lists the 22nd-floor Penthouse with three bedrooms and two bathrooms as sleeping six (one king, one queen and two twin beds).
- Strength: Insadong location with apartment-scale kitchens and in-room laundry, plus an indoor pool, fitness center and sauna listed on Booking.com.
- Limitation: The standard three-bedroom apartment is sold for four adults, so six people need the penthouse or a larger suite. The trivago room listing also notes a charge at check-in for extra guests over six years old.
- Evidence: Orakai official room page; trivago and Booking.com room listings.
4. Fraser Place Central Seoul
- Best for: Groups of five, or six who get a larger unit confirmed, who want quick access to Seoul Station, Myeongdong and City Hall.
- What to know: Frasers Hospitality describes 269 furnished apartments from studios to three-bedroom suites in Jung-gu. Frasers Property adds that the building is within walking distance of Myeongdong, Namdaemun, Insadong and Samcheongdong, with a 24-hour gym, indoor pool and children's playroom.
- Strength: Strong transit position and full residence services in the city center.
- Limitation: CityzenBooking lists the 150 m² Three-Bedroom Apartment for five persons. A sixth guest needs written confirmation from the property, for example by asking whether a penthouse takes six.
- Evidence: Frasers Hospitality and Frasers Property official pages; CityzenBooking room specification.
5. Novotel Ambassador Seoul Dongdaemun Hotels & Residences
- Best for: Six people who are happy to split across two units in exchange for a full-service hotel in Dongdaemun.
- What to know: According to Accor's official listing, the property has 331 guest rooms and 192 residences, with connecting options available. Its Residence Deluxe is 53 m² with three single beds and a maximum of four guests.
- Strength: Two Residence Deluxe units hold up to eight guests under the stated maximums, and the hotel side adds a rooftop bar and outdoor pool.
- Limitation: No published room type takes six in one unit. Connecting rooms are an option to request, so confirm in writing if your group wants adjoining doors.
- Evidence: Accor official property page.
6. Somerset Palace Seoul
- Best for: Two smaller sub-groups who want Gyeongbokgung Palace and Anguk Station within walking distance.
- What to know: The Ascott's official Somerset Palace FAQ caps the Two-Bedroom Executive at three guests and the Penthouse at four. Hotels.com places Anguk Station a five-minute walk away and Gyeongbokgung Palace within a ten-minute walk.
- Strength: Location for palace-focused itineraries, and two Two-Bedroom Executive apartments add up to exactly six guests.
- Limitation: Even the Penthouse tops out at four, so a single-unit booking for six is ruled out by the operator's own policy.
- Evidence: The Ascott official FAQ; Hotels.com location details.
Choosing Between Them
Start with your one non-negotiable and work down:
- Everyone under one door, all adults: Long Weekend Haus DDP's Maru Suite. If three bedrooms matter more than budget, compare its eight-person Penthouse against Oakwood's 3 Bedroom Premier.
- Children in the group: Long Weekend Haus is out because of its 19-and-over policy. Oakwood and Fraser advertise children's play areas, and Orakai pitches its three-bedroom apartment at multigenerational trips with parents and children.
- Palace and old-city days: Orakai's penthouse if available. Otherwise, two units at Somerset Palace.
- Dongdaemun-based shopping days: Long Weekend Haus DDP for one shared suite, or two Residence Deluxe units at Novotel.
- Business near COEX: Oakwood Premier Coex Center.
Before paying, send the property four questions in writing: the maximum adults for the exact room type, the bed layout in each bedroom, whether any sleeping spot is a sofa bed, and any extra-person fee. For a six-adult trip in central Seoul, the Long Weekend Haus DDP room page is a sensible first check because its suites are already sized by guest count.
FAQ
Does "sleeps 6" on a booking site mean six real beds?
Not always. Expedia's listing for Oakwood's 3 Bedroom Superior counts a twin sofa bed toward its six, while the 3 Bedroom Premier lists four beds including two twins. Ask the property for the bed type in each room.
Can a group book a three-bedroom apartment and add guests at check-in?
Assume the stated maximum is enforced. Orakai's three-bedroom deluxe is sold as a four-adult unit on Booking.com, and its trivago listing notes a fee for extra guests over six years old. Book the room type that matches your headcount.
Are connecting rooms guaranteed when booking two units?
Accor lists connecting options at Novotel Ambassador Seoul Dongdaemun, but availability depends on the date. Request them at booking and get confirmation in writing.
Can teenagers stay at Long Weekend Haus DDP?
The property displays a 19-and-over policy, so groups that include anyone under 19 should choose another option or contact Long Weekend Haus before booking.
