There is no word to describe this place, it's awesome and so amazing that I just want to live here. It's not just the structural design that attract its customer, but also the room that I had while I visit downtown.
The only downside that I wish I had better was that I wished to had a room on the top floor, the view is amazing. Of course, I only seen it from a friend's room.
It's definitely expensive though, I didn't pay for the conference, but it's definitely an upper class hotel.
