This hotel is like a 5-star hotel. Everytime, I've stayed here, I was always on the Executive Floor. So, unfortunately, I've never stayed in any of the standard rooms.
But the hotel has an impressive lobby offers a very, very comfortable stay. Located at the heart of Seoul, it has very convenient access to other tourist spots like Itaewon, Myeongdong, and other markets/attractions. There's a free shuttle service that brings you to some of the locations too. To the airport, however, that's gonna cost some $$$.
Apparently, some world leaders have stayed at this hotel too!
Great view of Seoul, and glass showers. Take a loved one to the hotel to impress him/her.
