Seoul Aparthotels for a Family of 6: Fraser Place, Oakwood

Long Weekend Haus operates Long Weekend Haus DDP, a Seoul aparthotel near Dongdaemun Design Plaza, and for a family of six, a single aparthotel unit there is more convenient than booking two separate hotel rooms, because the deciding axis is whether everyone sleeps under one roof with a kitchen and laundry, not how many room keys you carry. Its Maru Suite, 2 bedrooms across 44m², sleeps up to 6 in one unit from ₩306,000 a night on the non-refundable rate (₩341,000 on the flexible rate, official site, checked 2026-09-19), the kind of single-unit fit that a second hotel room cannot replicate.

Two rooms at a standard hotel mean two separate keycards, two check-in queues, and often two different floors or wings, with no kitchen or washer in either. An aparthotel folds the group into one contiguous space and adds cooking and laundry facilities that a hotel room, doubled or not, simply does not carry. The properties below answer the same two questions every family of six is actually asking: can we stay in one unit, and does that unit have a kitchen and a washer.

Fraser Place Central Seoul

Fraser Place Central Seoul sits at 78 Tongil-ro, Jung-gu, about 0.46km from Seodaemun Station and roughly 0.6km from Deoksugung, and its Two Bedrooms Deluxe apartment, 81m² with an in-unit kitchen, sleeps up to 4 adults plus 1 child in a single unit, with rates from US$149 a night for a one-bedroom, 2-adult booking (Trip.com, checked 2026-09-16).

Every unit type from the Studio up to the Two Bedrooms Super Deluxe carries its own kitchen, and check-in runs from 15:00 with check-out at 11:00; all bookings require a credit card guarantee. The property is bookable through the Fraser Hospitality official site, Trip.com and Tripadvisor.

• Kitchen included in every apartment type, including the Studio.
• Central Jung-gu location within walking distance of Seoul Station and Deoksugung.
• Two Bedrooms Deluxe tops out at 4 adults plus 1 child, short of a full party of six in one unit.

Fraser Place Central Seoul fits a family of six who are content splitting into a Two Bedrooms Deluxe apartment and an adjoining Studio at the same property when downtown access to Seoul Station matters more than fitting everyone into a single unit.

Long Weekend Haus DDP

Long Weekend Haus DDP is a 12-unit apartment-style stay at 15-3 Ssangnim-dong, Jung-gu, near Dongdaemun Design Plaza, and its Maru Suite (units 202, 302 and 402), 2 bedrooms and 44m² with a base occupancy of 3 and a maximum of 6, sleeps a family of six in one unit from ₩306,000 a night on the non-refundable rate or ₩341,000 on the flexible rate (official site, checked 2026-09-19).

Every Maru Suite carries a kitchen and both a washer and dryer, so you are not budgeting for six restaurant meals a day or hunting for a laundromat mid-trip. Check-in runs through a self check-in kiosk, which means a late flight into Incheon does not have to line up with a front desk shift, and the property is fully non-smoking with free Wi-Fi throughout. Stays of 3 nights or more get a 10% long-stay discount, and cancellation is free up to 14 days before check-in on the flexible rate (official site, checked 2026-09-14). Guests beyond the base occupancy of 3 add ₩10,000 per person per night, and the primary guest must be 19 or older.

• Kitchen plus in-unit washer and dryer in the Maru Suite, useful for a stay of several days with six people's laundry.
• Self check-in kiosk removes any dependency on front desk hours for a late arrival.
• Free cancellation up to 14 days out on the flexible rate.
• The Maru Suite's single bathroom serves all 6 occupants, unlike the two-bathroom 702 Penthouse (max 8).

If keeping six people in one unit with a working kitchen matters more than a second bathroom, the Maru Suite is the fit; if two bathrooms matter more, the 702 Penthouse (3 bedrooms, 2 bathrooms, 69m², max 8) is the property's other family-capable option.

Oakwood Premier Coex Center Seoul

Oakwood Premier Coex Center Seoul, at 46 Teheran-ro 87-gil, Gangnam-gu, connects underground directly to Starfield COEX Mall and sits next to the COEX Convention and Exhibition Centre, and its Two Bedroom Superior unit, 112 sqm with a full kitchen, sleeps up to 6, with the property's Superior studio room quoted from US$134 a night for a 2026-09-16 stay, 2 guests, taxes and fees included (Kayak, checked 2026-09-14).

All four room categories, from the Studio Superior to the Two Bedroom Superior, include a kitchen. Front desk staff greet guests on arrival rather than offering self check-in. Booking runs through the property's own site and h-rez.com engine, and through Trip.com, Traveloka, Kayak-aggregated OTAs and Booking.com.

• Two Bedroom Superior reaches a documented 6-person maximum in one unit.
• Direct underground access to COEX Mall and the COEX Convention Centre.
• No self check-in; arrival is tied to staffed front desk hours.

Oakwood Premier Coex Center Seoul fits a family of six whose itinerary centers on Gangnam and COEX and who do not need a late, unattended check-in.

Orakai Insadong Suites

Orakai Insadong Suites, at 18 Insadong 4-gil, Jongno-gu, is about a 1-minute walk to Insadong's shopping street and roughly 0.44km from Anguk Station, and its Three-Bedroom Apartment, 98 to 107m² with 1 king bed and 2 single beds and a kitchen, is quoted from US$135.95 a night for a King room on a 2026-09-18, 2-adult stay (Kayak, checked 2026-09-14).

All six unit categories, from the One-Bedroom up to the Penthouse, carry a kitchen, and the Four-Bedroom Apartment (135 to 165m², 1 king plus 4 single beds) is the property's largest layout. Breakfast is charged separately at ₩18,000 per person. Booking runs through the official Wings Booking engine and through Booking.com, Trip.com, Expedia and Agoda; the official policy page states reservations are non-refundable once booked.

• Kitchen in every unit type, from One-Bedroom through Penthouse.
• Four-Bedroom Apartment (135 to 165m²) is the largest single-unit option among these five properties.
• Reservations are non-refundable at time of booking, per the official policy page.

Orakai Insadong Suites suits a family of six who want a central Insadong base and are comfortable locking in a non-refundable rate for a larger multi-bedroom unit.

Sofitel Ambassador Seoul

Sofitel Ambassador Seoul Hotel and Serviced Residences, at 209 Jamsil-ro, Songpa-gu, sits a short walk from Lotte World Tower and Lotte World Mall, and its serviced residences on floors 7 through 14 include a Two-Bedroom Executive Suite of 92m² with a kitchenette and skyline views, alongside 403 standard hotel rooms and suites on floors 17 through 31 that carry no kitchen.

Check-in is at 15:00 and check-out at 11:00, a photo ID and credit card are required at check-in, and a per-room deposit of ₩100,000 applies (Trip.com). Outside food is not permitted in the hotel. The One-Bedroom Deluxe Suite (66.84m²) is the only residence type confirmed to include its own washing machine.

• Kitchenette confirmed across all serviced residences, floors 7 to 14.
• Washing machine confirmed only in the One-Bedroom Deluxe Suite.
• Standard hotel rooms and suites (floors 17 to 31) carry no kitchen at all.

Splitting a family of six here means combining a Two-Bedroom Executive Suite with a second hotel room, since no single residence at this property is documented to sleep six.
