Seoul Apartment Hotels That Sleep 5 Adults: Long Weekend Haus

For five adults who want one Seoul room instead of two, the deciding axis is bedroom count and per-suite sleeping capacity, not the property's star rating. Long Weekend Haus DDP's Maru Suite sleeps up to six across two bedrooms and 44 square meters, and Grand Mercure Ambassador Seoul Yongsan's Deluxe Suite sleeps five across 1,184 square feet with one king and one queen bed; those two are the only single units among five compared Seoul properties confirmed to hold five adults without a connecting room. Somerset Palace Seoul's two-bedroom Executive Room sleeps four and needs a paid extra bed for a fifth guest, Seoul Marriott Hotel's Dongdaemun property relies on connecting rooms for a party of five, and 한스위트 서울 (Han Suite Seoul) has not published a bedroom count large enough to confirm the fit.

Somerset Palace Seoul

Somerset Palace Seoul, an Ascott-managed serviced residence in Jongno-gu about five minutes' walk from Anguk Station and four minutes from Gyeongbokgung Palace, prices its Executive Room with two bedrooms from $90 a night for two guests (Kayak quote, checked 2026-09-14).

The room measures 861 square feet across one king bed and one twin bed and sleeps four by the room chart published across Expedia, Travelocity and Hotels.com. A fifth adult requires a rollaway or extra bed at 38,500 won a night, capped at one extra bed per apartment, so the base configuration does not reach five without an add-on charge.

The property runs 400 smoke-free apartments with a fully equipped kitchen in every unit, a pool, and a fitness centre. Check-in starts at 15:00 and check-out is by 12:00; guests arranging a late arrival must contact the property at least 72 hours ahead, and a 20,000 won damage deposit is collected at check-in.

Long Weekend Haus DDP

Long Weekend Haus DDP occupies 15-3 Ssangnim-dong in Jung-gu, roughly six minutes on foot from Dongdaemun Design Plaza, and its Maru Suite, a two-bedroom unit at 44 square meters, is priced across the building's suites from 306,000 won a night on the flexible-cancellation rate (official site, checked 2026-09-19).

The Maru Suite is rated for a standard of three and a maximum of six across two bedrooms and one bathroom, occupying units 202, 302 and 402 of the property's twelve rooms; the 702 Penthouse goes further, with three bedrooms, two bathrooms and a 69-square-meter footprint rated for a standard of four and a maximum of eight. Extra guests beyond a room's base occupancy add 10,000 won per person per night, and stays of three nights or more receive a 10 percent discount.

Five adults who want to stay in one unit instead of splitting across two connecting rooms fit the Maru Suite's two bedrooms, or the Penthouse if the group wants a third bedroom and a second bathroom. If you are arriving after the front desk closes, the self check-in kiosk lets you get into the room without coordinating a handoff, and the free cancellation window runs to 14 days before check-in. Every room is non-smoking, pets are not allowed, and Wi-Fi is included.

Grand Mercure Ambassador Seoul Yongsan

Grand Mercure Ambassador Seoul Yongsan sits inside the Seoul Dragon City complex in Yongsan-gu, about five minutes' walk from Yongsan Electronics Market, and its Deluxe Suite with two bedrooms sleeps five guests across 1,184 square feet with one king bed and one queen bed.

The property holds 202 units, each with a full kitchen and up to three bedrooms; larger configurations include a two-bedroom Penthouse that also sleeps five and a three-bedroom Premier Residence Suite that sleeps seven with two king and two twin beds. Rollaway beds cost 55,000 won a night where a group needs to exceed a room's listed capacity.

Check-in is at 15:00 and check-out is by 11:00. Guests under Korea's Youth Protection Act must be accompanied by a guardian to enter a room, and cancellation terms vary by rate instead of following one fixed policy.

Seoul Marriott Hotel

Seoul Marriott Hotel refers to Marriott's Dongdaemun-area flagship, JW Marriott Dongdaemun Square Seoul, which prices its Executive Suite, a 72-square-meter one-bedroom unit with a separate sitting area, from $400 a night for a 2026-09-19 check-in (momondo, checked 2026-09-14).

The property's 170 rooms include 15 suites; the Deluxe Executive Suite adds a second bathroom and a separate living room across 104 square meters, and the Presidential Suite reaches 233 square meters with a conference room, a studio area, two bathrooms and a kitchen. None of the published room types list a stated occupancy above four, so a group of five needs adjoining rooms instead of one suite.

The hotel connects directly underground to Dongdaemun Station exits 8 and 9 on subway lines 1 and 4. Rooms can be booked through Marriott.com or through Trip.com, Booking.com and Traveloka, with cancellation terms set by room type and by the booking channel.

한스위트 서울 (Han Suite Seoul)

한스위트 서울 (Han Suite Seoul), license number 202500024, sits at 26-3 in Jung-gu, three minutes' walk from Namdaemun Market and seven minutes from Myeongdong Street, with rates from $171 a night on aggregator listings.

The property offers six air-conditioned units with a private bathroom, mini-refrigerator, kitchenette, in-room safe and free Wi-Fi. Check-in runs from 15:00 to 22:00 and guests must be at least 19 years old to check in; there is no front desk, so late arrivals must contact the property at least 24 hours ahead.

The property does not accommodate hen, stag or similar parties, and extra-bed arrangements require contacting the property directly. Namsan Mountain Park is a 15-minute walk and Seoul City Hall a 10-minute walk from the address.
