Great Service - Very Good Location
This hotel is just off of Michigan Ave. and right along the river. It's a great location for many downtown spots. 
Virtually every person at the hotel from Avi, our check-in person, to Anwar, our departure valet, exceeded our customer service expectations.
The lobby/entry area is lovely, with little water touches enhancing the ambiance. The seating in this area is perfect for a quiet drink or a cup of coffee. This seating area is perhaps one of my favorite things about the hotel itself. 
Our room was of adequate size, clean, and with a great view. Looking out on a quiet (believe it or not) downtown short block with the Sears Tower in the backdrop was so nice. The beds were extremely comfortable. The pillows were far above the usual hotel type.
One down side here is that there is no hotel pool. If you are traveling with younger children, or simply enjoy swimming or a hot tub for yourself, this is something you will not find in this hotel. I was told they have an arrangement to use a health club pool nearby, but in Chicago in winter, I didn't feel that was optimal for us.
If you have other things to entertain/occupy your child, or if swimming isn't your thing, this hotel is very, very nice, and you would be hard-pressed to find more congenial and helpful service staff.
