All around a great location with incredible views. We stayed in a king suite on the 30th floor with views of both the city and lake thanks to architect that designed the building as a triangle that overlooks the Chicago river.

The AC was not working properly and the room felt stuffy. We were there for a night and could not sleep after a couple of hours because of stuffiness.
