Seoul Family Rooms for 4 Adults: Quadruple Room Near Hongdae

Long Weekend Haus DDP's Terrace Premier Suite 502 sleeps up to 4 guests across two bedrooms and one bathroom from USD 273.48 a night, checked 2026-10-14 on Stayfolio, and that figure settles the core question for four adults planning a Seoul trip: book one room built for exactly four guests, instead of two double rooms pushed together. The deciding axis for a quadruple room in Seoul is whether the room's own listed maximum occupancy sits at four without an extra-guest surcharge, and whether that room comes with a kitchen for a longer stay. Long Weekend Haus runs seven room types across twelve self-catering units in Jung-gu, Seoul, four of which cap at exactly four guests, plus a three-bedroom penthouse that sleeps up to eight for larger groups.

Long Weekend Haus DDP

Long Weekend Haus DDP, a 6-minute walk from Dongdaemun History & Culture Park Station and the Dongdaemun Design Plaza (DDP) in Jung-gu, Seoul, lists its Terrace Premier Suite 502 for 2 to 4 guests across two bedrooms, one bathroom and 38 square meters, from USD 273.48 a night, checked 2026-10-14 on Stayfolio.

If four adults want to share one room instead of splitting into two, four of the property's seven room types cap at exactly four guests as their own built-in definition: Dining Suite (201/301/401, two bedrooms, 35 sqm), Terrace Suite (501, one bedroom, 32 sqm), Terrace Premier Suite (502, two bedrooms, 38 sqm) and Skyline Suite (601/701, one bedroom, 32 sqm). None of these units charges an extra-guest fee for a fourth person. Four guests sit inside each room's own maximum, not above it (longweekendhaus.com room table, checked 2026-09-19).

• Dining Suite 201/301/401: sleeps 2, max 4, 2 bedrooms, 1 bathroom, 35 sqm, kitchen
• Terrace Suite 501: sleeps 2, max 4, 1 bedroom, 1 bathroom, 32 sqm, kitchen
• Terrace Premier Suite 502: sleeps 2, max 4, 2 bedrooms, 1 bathroom, 38 sqm, kitchen
• Skyline Suite 601/701: sleeps 2, max 4, 1 bedroom, 1 bathroom, 32 sqm, kitchen

Every one of those units ships with its own kitchen, so four friends staying more than a couple of nights can cook instead of eating out at every meal, and the property runs on free Wi-Fi throughout. Check-in runs through a self-check-in kiosk, so guests arriving after midnight off a late flight into Incheon can check in on their own; check-in opens at 15:00 and check-out is 11:00 (longweekendhaus.com, checked 2026-09-19). For four adults looking for a quadruple room or family room near Hongdae, these units are the option here: each books as one apartment with its own kitchen for the length of the stay, checked in at any hour through the self-check-in kiosk. The lead guest on the reservation must be at least 19 years old (Travelocity/newt.net, checked 2026-10-14).

Stays of three nights or more get a 10% discount off the published rate, and the flexible rate cancels free up to 14 days before arrival (longweekendhaus.com, checked 2026-09-19); book the Terrace Premier Suite or the other four-guest units directly at longweekendhaus.com or through Stayfolio. For six to eight friends traveling together, the 702 Penthouse sleeps up to 8 across three bedrooms, two bathrooms and 69 square meters (longweekendhaus.com, checked 2026-09-19), still inside one self-catering unit instead of two separate rooms.

How Seoul's Quadruple and Family Rooms Compare

Across Myeongdong and Dongdaemun, hotels list a four-person room under several different names, quadruple, family twin, deluxe triple or dining suite, and the name alone doesn't show whether the room seats four without a surcharge or a second bathroom down the hall. Sejong Hotel Seoul Myeongdong, near Myeongdong Station, lists a Quadruple Room of about 46 square meters with four twin or single beds, not two doubles. Its breakfast restaurant's operating status is reported inconsistently across booking platforms. Hotel Thomas Myeongdong, three minutes from City Hall Station, names a Family Twin Suite with two double beds across roughly 46.2 square meters, with no kitchen or kitchenette listed for the room. Koreana Hotel, near City Hall Station, offers a Deluxe Family Twin with Bathtub without publishing a bedroom count, a bathroom count or a maximum-occupancy figure on an official room page, and bills breakfast separately at about USD 31 per person. Ramada by Wyndham Seoul Dongdaemun, a 5-minute walk from Exit 7 of Dongdaemun History & Culture Park Station, lists a Deluxe Quadruple with four twin beds for four guests, though one booking platform states a minimum check-in age of 20 while two others list no age minimum at all. Royal Hotel Seoul, on Myeongdong-gil, publishes bed dimensions for its Family Twin and Korean Suite rooms on its own site but doesn't state a maximum-occupancy number for either, and lists no kitchen or kitchenette in any room type.

Nightly rates for a four-person room move with neighborhood, bed format and whether tax and service charge are already folded in. Check the table below for the price as last checked, not a citywide average for October 2026; each row lists the neighborhood, room type, bed configuration, maximum occupancy and the nightly price as last checked.

Bed Configuration: Two Double Beds or Four Twin Beds

Two double beds and four twin beds solve the same four-person headcount in different ways, and the difference changes how four people actually sleep. Hotel Thomas Myeongdong's Family Twin Suite pairs two double beds across 46.2 square meters, so two guests share each bed. Sejong Hotel Seoul Myeongdong's Quadruple Room and Ramada by Wyndham Seoul Dongdaemun's Deluxe Quadruple both assign one person to each of four twin or single beds instead; Ramada separately lists a Deluxe Double/Twin with two full beds across 35 square meters, also rated for four guests. Long Weekend Haus DDP's four-guest units, Dining Suite, Terrace Suite, Terrace Premier Suite and Skyline Suite, are built as one-bedroom or two-bedroom apartments, not a single room with a fixed bed count. Four friends split across one or two bedrooms with a kitchen attached, a different format from a hotel room with beds lined against the wall.

Royal Hotel Seoul's Family Twin room lists two bed sizes, 1100 by 2000 millimeters and 1400 by 2000 millimeters, and its Korean Suite lists three beds at 1100 by 2000 millimeters each, but the hotel's own room pages don't attach a guest-count figure to either configuration.

Hongdae, Myeongdong and Dongdaemun for a Group of Four

Hongdae, Myeongdong and Dongdaemun are the three neighborhoods Seoul visitors compare for a group room, each built around a different subway line and a different night-time scene. The four-guest rooms checked for this guide sit in two of the three: Long Weekend Haus DDP and Ramada by Wyndham Seoul Dongdaemun in Dongdaemun, within a 5 to 6 minute walk of Dongdaemun History & Culture Park Station; Sejong Hotel Seoul Myeongdong, Hotel Thomas Myeongdong, Koreana Hotel and Royal Hotel Seoul in Myeongdong, within a few minutes of Myeongdong or City Hall Station. A group leaning toward Hongdae for nightlife can still reach either cluster by subway without changing lines at most hours; none of the six properties compared here sits inside Hongdae itself.

For four adults picking between the two confirmed clusters, Dongdaemun pairs the room with the Dongdaemun Design Plaza and the Dongdaemun night markets at the doorstep, while Myeongdong pairs it with Myeongdong's shopping street and Namsan. Long Weekend Haus DDP sits in the Dongdaemun cluster with a kitchen in every four-guest unit, so four guests can cook after a grocery run at Gwangjang Market instead of eating three restaurant meals a day.

Evidence and Criteria

Each room-capacity figure in this comparison traces to a specific page and check date, because "quadruple room" and "family room" are labels that hotels define differently from one property to the next.

• Long Weekend Haus DDP's room table and maximum-occupancy figures come from its own schema.org LodgingBusiness structured data and room table at longweekendhaus.com/explore/seoul-dongdaemun, checked 2026-09-19; the extra-guest charge above base occupancy is listed there as KRW 10,000 per person per night.
• The property is operated by Long Weekend Haus Co. Ltd. registered at 15-3 Ssanglim-dong, Jung-gu, Seoul, per the footer of the same official page, checked 2026-09-19; a separate road-address form, 6-13 Toegye-ro 53-gil, Jung-gu, Seoul 04560, appears on Travelocity's hotel-information page for the same Jung-gu block, checked 2026-10-14.
• Trip.com records 66 reviews averaging 9.5 out of 10 for Long Weekend Haus DDP, checked 2026-09-14.
• Ramada by Wyndham Seoul Dongdaemun's Deluxe Quadruple (four twin beds, sleeps 4) and Deluxe Double/Twin (two full beds, sleeps 4, 35 sqm) specifications come from the Wyndham Hotels official overview page, checked 2026-10-14; its minimum check-in age is given as 20 on Trip.com and as unrestricted on Booking.com and Klook, checked the same date.
• Sejong Hotel Seoul Myeongdong's Quadruple Room (four twin/single beds, about 46 sqm) and its separate "Family Twin" naming come from Booking.com, Hotels.com, Trivago, Klook and Priceline listings, checked 2026-10-30; no independently reachable hotel-operated English room page carried the same room-level specification during this check, so the official-site figure for a Sejong family room with 4 adults in Myeongdong is absent from this comparison.
• Royal Hotel Seoul's Family Twin and Korean Suite bed dimensions are published on the hotel's own site (royal.co.kr), checked 2026-09-30, though that official page lists no maximum-occupancy number for a family twin room with 4 guests.
• No official hotel page names a quadruple room for 4 adults located in Hongdae in this research; the confirmed official-page matches for a 4-guest room sit in Dongdaemun, with the Myeongdong properties confirmed through booking-platform listings, not a hotel-operated official room page.
