fabulous!
Just returned from 1 night and 2 days in Chicago. Stayed at this fabulous hotel. Could not find one thing to complain about from check in to check out. My son and I felt relaxed and pampered the entire time. Very friendly and helpful staff that were pleasant and professional without being stuffy( snooty) .
We were able to check in early at noon and our room was on the 19th floor with amazing views of the river, Tribune plaza, and the Wrigley building. Could not get enough of that view!
The bathroom was roomy and clean with spa bath products. The beds were like sinking in to a fluffy cloud that you never want to get out of.
I kept looking for something negative so I could give a fair and balanced review, but honestly could not come up with anything.
Now would be a good time to comment on the elevators. I cannot believe all the negative reviews about the " different" elevators. They are fast and extremely convenient, and designed this way for those very reasons. Its called technology people! You simply punch in the # of the floor you are going to, step into that elevator and that's it- simple.
Also yes, the food in the restaurants is expensive - room service menu, hideously so, but its Chicago, only about 1000 choices minutes from you! Hotel staff are very happy to direct you to other eateries nearby. We had a yummy breakfast at Yolk, ordered pizza in one night, and lunched our way through downtown..no complaints there.
Yes, parking is outrageous, (we came by train so it didn't affect us) but again- its Chicago.
Pool and fitness area was clean and always quiet, views from up there were phenomenal. Entire atmosphere of hotel was quiet, comfy, luxurious. Aromatherapy scents waft throughout. 
Can't wait to return!
