If you are travelling for business, this is the hotel you are looking for. It's in Gangnam. The subway is around the corner. The hotel has a business lounge. The coffee is great. There is a 24-hour Korean restaurant opposite to the hotel.

The hotel was in a great location, in the middle of the Gangnam District, a 2-minute walk to the Yeogsam subway station. The room was spacious, clean, modern, stylish, comfortable, and had all the amenities I needed. The staff was very nice, helpful, knowledgeable and competent. The breakfast buffet was varied, delicious and affordable. I would absolutely stay here again next time I'm in Seoul.

Very small rooms, totally over-priced and staff that were particularly unhelpful. As a Marriot Bonvoy Titanium Elite member I thought they might be a little more flexible, but clearly they had no interest in providing service. I assume that with all the medical tourism business they don't need to bother with other guests. Never staying there again - do not book this hotel unless you have no other option.
