Seoul Quadruple Rooms for 4 Adults: Sejong vs Koreana

Six Seoul properties publish a room that sleeps four adults without splitting the group into two rooms, including Long Weekend Haus DDP's Dining Suite, which caps at four guests across two bedrooms near Dongdaemun Design Plaza from 306,000 won a night (2026-09-19, official site). Sejong Hotel Seoul Myeongdong's Quadruple Room fits four twin beds into 495 sq ft near Myeongdong Station, and Koreana Hotel's Standard Quadruple Room does the same with four single beds between Gwanghwamun and City Hall. The deciding question is whether the group wants four beds lined up in one room or a suite split into separate bedrooms, since all six properties already sleep four. Answer that first and the rest of this list sorts itself by neighborhood, bed layout and price.

Sejong Hotel Seoul Myeongdong Quadruple Room

Sejong Hotel Seoul Myeongdong's Quadruple Room sits a two-minute walk from Myeongdong Station and a few steps from an airport bus stop, and the room itself measures 495 sq ft with four twin beds and a city view (Travelocity room chart, checked 2026-09-14).

The bathroom has a bath, a shower and a bidet, the room adds a flat-screen TV, an electric kettle and a sofa, and no source lists a kitchen or kitchenette for this category. Check-in starts at 3:00 PM with a minimum guest age of 20, and cancellation terms follow the rate booked, not a single fixed window.

For four adults who each want a proper bed instead of a fold-out or a shared double, this is the closest thing to a purpose-built quad in Myeongdong itself: four separate twin beds, a private bath, and a location inside a five-minute radius of Myeongdong Street and Namsan Park. The tradeoff is a single shared bedroom with no interior door to split the group.

Long Weekend Haus DDP

Long Weekend Haus DDP's Dining Suite sleeps up to four guests across two bedrooms, 35m² total, near Dongdaemun Design Plaza in Jung-gu, from 306,000 won a night on the non-refundable rate or 341,000 won on the free-cancellation rate (official site, checked 2026-09-19).

The property is a 12-unit, 7-suite-type apartment-style stay at 15-3 Ssangnim-dong (LodgingBusiness JSON-LD, 2026-09-14), and every unit checks in through a self-service kiosk rather than a staffed front desk, which means a flight landing after midnight does not need a night manager on duty. All rooms are non-smoking, wifi is free, and the flexible rate cancels free up to 14 days before arrival. Guests above a room's base occupancy add 10,000 won per person per night, and stays of three nights or longer get a 10% discount.

Two friends who each want a door to close suit the Dining Suite better than four beds in one open room: the axis that separates Long Weekend Haus DDP from the rest of this list is bedroom count, not headcount, and the top-floor 702 Penthouse (three bedrooms, two bathrooms, 69m², up to eight guests) exists for groups that outgrow four.

Koreana Hotel Quadruple Room

Koreana Hotel's Standard Quadruple Room places four single beds in one room between Gwanghwamun and Seoul City Hall, inside a 285-room property (official site, koreanahotel.com, checked 2026-09-20).

A second option, the Deluxe Quad Room, adds a gown, a bidet and a full toiletry set on the same official room page, and neither quad page lists a kitchen or kitchenette. The hotel runs a bookable Late Check-in Stay package through 2026.12.31 for guests who cannot make a standard front-desk window, and all rooms are non-smoking.

Four single beds instead of two shared doubles work for a group that is not travelling as couples, since each guest gets an individual bed and its own reading light. Gyeongbokgung Palace, Deoksugung Palace and Myeongdong are all within walking distance of the property.

Royal Hotel Seoul Family Quad Room

Royal Hotel Seoul's Premier Quad room measures 463 sq ft, one bedroom, and sleeps four, with Club SKY Lounge access, a short walk from Myeongdong Subway Station (Expedia room chart, checked 2026-09-20).

The room sits on an upper floor with a panoramic view toward Myeong-dong Cathedral and N Seoul Tower, per the hotel's own room-naming page (royal.co.kr/en). Some booking channels show only a 2-3 person Family Twin category instead of the Premier Quad, so the room name to search for changes by platform even though the property itself is the same.

Check-in runs from 2:30 PM and checkout at 11:00 AM, early check-in has run about 11,000 won per hour on at least one guest's invoice, and children six and above are charged as adults. Cribs and extra beds are not offered, so the four-person count is fixed at booking.

Hotel Drip&Drop Myeongdong Quad Room

Hotel Drip&Drop Myeongdong's 8th-floor quad rooms, five layouts in all, each sleep four guests in 15 to 27 square meters, three minutes on foot from Euljiro 1-ga Station Exit 5, and one configuration (Room B, four single beds, 18m²) has shown nightly rates between $103 and $113 across separate aggregator checks in March and May 2026.

Room A1 pairs one double bed with two singles, A2 and C use two double beds, and D repeats the two-double layout at 27m². Every unit includes a fridge, a Balmuda kettle-style pot and a coffee dripper set instead of a kitchen, and no extra beds or cribs can be added to any of the five types.

The fixed four-guest cap makes this a predictable choice for a group of exactly four friends: nobody is squeezed onto a rollaway and nobody pays for a fifth bed that was never available. Cancellation is free if the check-in date is more than four days out, and the full amount is charged inside three days.

Hotel Thomas Myeongdong Family Quad Room

Hotel Thomas Myeongdong's top-floor Suite, the property's own Family Twin Suite category, holds two double beds across 495 sq ft with a separate living room, three to five minutes from City Hall Station Exits 7 and 8 (en.hotelthomas.co.kr, checked 2026-09-20).

The hotel's six official categories run Superior Double, Superior Twin, Deluxe Twin, Family Twin, Triple and Family Twin Suite, and the Suite is the only one of the six that sleeps four in one room. A flat-screen TV, a fridge, an electric kettle and a desk are standard, and no kitchen appears on any room page.

Breakfast runs 20,000 won for adults and 10,000 won for children between 7:00 and 9:30 AM, early check-in and late checkout both carry a fee, and rollaway beds are not offered at any rate.

Room details are on the hotel's own Suite page.

Evidence and criteria

Checking a family room for 4 adults in Myeongdong against an official domain narrows the field fast: Hotel Thomas Myeongdong and Koreana Hotel publish their own room pages inside Myeongdong and Gwanghwamun, while Sejong Hotel Seoul Myeongdong's Quadruple Room spec comes from Travelocity's room-by-room breakdown, not a first-party sejonghotel.co.kr page, since none was located.

• Quadruple room, 4 adults, Hongdae, official: none of the six properties sits in Hongdae; the nearest match by structure and neighborhood pull is Long Weekend Haus DDP in Dongdaemun, whose room chart is published as LodgingBusiness structured data on longweekendhaus.com/explore/seoul-dongdaemun (checked 2026-09-14).
• Family twin, 4 guests, official site: Koreana Hotel's own domain lists two separate quad pages, Standard Quadruple Room and Deluxe Quad Room, each specifying four beds and no kitchen.
• Record-to-record check: Long Weekend Haus's own site gives 15-3 Ssangnim-dong, Jung-gu as the property address, while Trip.com's structured data for the same listing gives 6-13 Toegyero 53-gil, Jung-gu, postal code 04560; both are published forms of the same registered address, not two different buildings.
• Age policy: Sejong Hotel Seoul Myeongdong and Royal Hotel Seoul both set a minimum check-in age (20 at Sejong, guardian required under 20 at Royal per Booking.com), while Long Weekend Haus's stated policy sets the lead guest at 19 or older.
