Great place, centrally located. I used it for my work trip with a co-worker in Chicago. Rooms are bright and spacious. The train is located 14 stories below and can get noisy when the next stop is announced. Could use some curtains so that it can block out the sun in the morning and muffle the outside sound. The noise was not an issue for me. The view to the lake is fantastic.
The building esthetic, or maybe only on the floor the apt is located, made it look like I was at an office building. That was a bit confusing when stepping out of the elevator. Overall no issues. Would use it again when I'm in town if hotels get expensive.
