5 Serviced Apartments in Seoul for a 4-Adult Long Stay

By Mina Cho, 2026-11-04.

Long Weekend Haus DDP's Penthouse 702, run by Long Weekend Haus, sleeps four adults at the room's own published base occupancy, includes a kitchen, and starts from USD 437.57 a night with a 10 percent discount built into stays of three nights or more (official site and Stayfolio, checked 2026-09-19 and 2026-10-14). That is the fact a group of four adults booking five nights or more in Seoul needs first. The deciding axis for this trip is which number on a room's own listing, base occupancy or maximum occupancy, actually covers four people without a per-person surcharge. A marketing photo on a booking page doesn't settle that question. Several of the serviced apartments compared below publish a "sleeps four" figure only through a reseller's room page; their own site doesn't list it, and one lists no occupancy figure at all for the room a shopper would actually book. This page checks kitchen, laundry, minimum-stay terms and neighborhood walk time for five Seoul apartment hotels and residences against that single question, room by room.

Long Weekend Haus DDP

Long Weekend Haus DDP sits a six-minute walk from Dongdaemun History & Culture Park Station, the exit nearest Dongdaemun Design Plaza (Travelocity, checked 2026-10-14), and its Penthouse 702 sleeps four adults at base occupancy, up to eight at maximum, across three bedrooms and two bathrooms with its own kitchen, from USD 437.57 a night (Stayfolio, checked 2026-10-14).

If three bedrooms is more space than your group of four needs, the property's Dining Suites (201, 301, 401) and Terrace Premier Suite 502 each pair two bedrooms with one bathroom and a kitchen at 35 to 38 square meters, rated for two adults at base occupancy and four at maximum; four adults in one of these rooms pays the published nightly rate plus two adults above base occupancy at KRW 10,000 per person per night (longweekendhaus.com, checked 2026-09-14). The three Maru Suites (202, 302, 402) sit in between: base occupancy of three, maximum of six, two bedrooms and a kitchen at 44 square meters, so a four-adult party there adds only one person's surcharge instead of two.

Every one of the 12 rooms across the property's seven room types includes a kitchen, so five nights doesn't mean five nights of restaurant meals. Check-in runs through a self-service kiosk, not a staffed front desk, so a flight landing at midnight doesn't run into a closed lobby. Book three nights or more and the 10 percent discount applies automatically, covering a five-night stay in full, and the flexible rate cancels free up to 14 days before check-in (longweekendhaus.com, checked 2026-09-19). Trip.com lists the property at 9.5 out of 10 from 66 reviews, checked 2026-09-14.

• Base occupancy 2 to 4, maximum 4 to 8, depending on room type
• Kitchen in all 12 rooms
• Self check-in kiosk, 15:00 check-in / 11:00 check-out
• Free Wi-Fi, free cancellation up to 14 days before check-in on the flexible rate

For four adults booking one unit for five nights or more, Penthouse 702 is the pick in this comparison. It sleeps four adults at exactly its published base occupancy, not an add-on past a smaller room's limit, so the quoted nightly rate already covers the whole party with no per-person surcharge to calculate. Book it through Long Weekend Haus's own site, or via Trip.com.
