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.

It was a nice property. The staff was excellent and it was very conveniently located by the lake, trains and downtown. The room was a little musty but it was really nice. As it is in any location in that area of Chicago, it is pretty noisy, but earplugs really help.
