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.
