We stayed for 6 days on holiday.
The hotel is perfectly located for your first visit to Seoul with good transport links and within walking distance of lots of attractions: shopping, palaces, modern buildings, Namsan park and restaurants.
We stayed in an executive floor room which is worth paying extra for. The rooms are a good size. We had one with a refurbished bathroom with a large walk in shower instead of a bath which was very nice.
Usual nice extras - bathroom products, bathrobes, water etc. Also free wifi in the room and a nespresso machine.
The executive lounge is large but still gets busy. We had to wait a few times for a table at breakfast and in the evening. The breakfast is very good with a large selection of hot and cold food. In the evening the nibbles are sufficient for a light dinner. Good choice of wines, beer etc.
We didn't use the hotel restaurants because there are lots of very good value places near the hotel. The staff in the executive lounge were happy to recommend and help with bookings.
The gym is huge and very well stocked with everything. As we found at other hotels in Korea there is free to hire gyn kit and the sauna area with pools, steam room, sauna and relaxation areas were excellent.More
