Within walking distance of everything
If you enjoy walking, this is a great place to stay because you are going to be close to everything. It is literally (not in the real estate broker sense) steps from Michigan Ave which is where all the stores are. You way want to walk in the other direction if you have a shopaholic in your party. Just saying.
Other than the great location, the staff was very friendly when we checked in and any time we had questions. We had to have a refrigerator and a microwave brought up to our room but they only charged us for one of the items even though there was supposed to be a fee for each (if this was a mistake...thanks anyway. It's the $25 bucks, not the thought that counts). 
We were upgraded to a corner suite on the 22nd floor which we were pleased with. Since other buildings are also really tall in the area, we really couldn't see much but we were pleased. Ask for an upgrade just to see what happens. 
The 40th floor pool was very cool even though it was tiny. The views are nice up there though. 
Our suite was a living area and a bedroom. Bigger than most Manhattan apartments. Manhattan, NY that is because If you are from Manhattan, KS, the suite is probably the size of your closet. Oh, it was clean too. I know this really shouldn't need saying but we have all been in hotel rooms that smell a little off or with discolored sheets. 
Overall, this is a greatly situated hotel with good service and nice views from higher floors. I recommend.
