Nice city hotel
I've stayed in many of the hotels in downtown Chicago for business, but this was a first to theWit. Overall a very good stay. It is located in the theater district - so a close walk to see A Christmas Carol at the Goodman. Location is great - tons of shopping and restaurants. Like other city hotels it is best to take advantage of valet parking and save yourself the headache. Helpful and friendly staff. And as another review mentioned - rooms are clean and comfortable. The beds were perfect! We were not upgraded though I am an Honors Member.
We did take a ride to the top to see the bar and the view. Since we had our 12 year old with us, we just peeked. The view is beautiful.
The only issue I found dealt with the key cards in the elevator. Because the elevator is used by the public to get to the bar guests need to insert a key card to access their floor. I am totally in favor of the extra safety, but it's not easy to quickly insert the key (the right way) and floor number before you've either missed your floor or gone in the wrong direction. This happened several times and got to be a bit annoying. 
Overall this is a good find and would recommend to others.
*** The halls have the sound of birds chirping during the day and crickets in the evening and night - loved it!
