Inside Seoul’s latest wellness and events hotel

The Westin Seoul Parnas has opened in the heart of Gangnam on 15 September 2025, adding 1,127sqm ballroom, two-storey fitness club, and other facilities to the South Korean capital city.

The hotel features 564 guest rooms, ranging from standard rooms to Presidential Suites across eight room types. Room layouts are optimised for business travellers, while spacious suites cater to long-stay guests and families.

Around a quarter of the inventory, or 144 keys, are Club Rooms. Club Room guests can access the 702-sqm Westin Club lounge on the top floor – with panoramic views of the Han River and Seonjeongneung – complete with private meeting rooms for smaller gatherings.

The hotel caters to corporate gatherings of different sizes, with seven meeting and event spaces that can accommodate 50 - 1,200 pax theatre style.

A highlight s the Harmony Ballroom, a 1,127sqm pillarless space that can host up to 1,200 guests in theatre set-up and 600 for banquets. The venue features a 5.3m ceiling height, LED media wall and advanced AV systems.

Another key feature of the urban wellness property is the Cosmopolitan Fitness Club. Spanning 6,000 sqm over two floors, it features “state-of-the-art” fitness equipment and tailored programmes, which can help long-stay guests and international delegates seeking continuity or structure in their health routines. In addition to Premium Technogym machines, a golf swing analyser and AR-based putting training systems, the fitness club also offers personalised nutritional consulting, personal training and group classes.

F&B concepts include an all-day dining restaurant; a “5-in-1” Asian restaurant serving up cuisines with Korean, Japanese, Chinese, Indian and Middle Eastern influences; a lounge and bar space; a wine archive; and a lifestyle concept featuring curated bakery, deli and other goods.

The property is also the first in Korea to adopt Marriott’s Digital Customer Experience mode which integrates guest services across check-in, in-room dining, wellness programmes bookings, and meeting support into a single mobile platform. The model can also improve guest experiences by responding to real-time feedback and predicting congestion in hotel spaces.

Part of the Marriott Bonvoy programme, the urban wellness hotel joins The Westin Josun Seoul and The Westin Josun Busan as Marriott International expands its footprint in South Korea’s premium wellness segment.
