I stayed there recently and was satisfied, not impressed though. The staff was curious, but not overly pleasing. I had to wait about 10-15 minutes in line to check in on a Friday evening (7pm) as they only had two people checking us in. Then 4 more came out of the woodwork, as if they had been on a break. After that, it was a nice weekend stay, easy access to my car in the valet garage, and easy access to 'shopping, wining & dining.' The rates were reasonable as well.
Pros: Close to Michigan Ave, Comfortable, Great View
Cons: needed more staff, lines
