9.4/10 Exceptional! (3,496 reviews)
Great location right off of Michigan Ave. They have a very good breakfast, that included almost everything you could want. It was very popular and packed with people. One negative, it felt like it was a cafeteria and not a relaxing place to sit down, relax and enjoy.

Beautiful old historical hotel. The rooms were clean. We had a fantastic view of Lake Michigan. There were a few things that would have made me want to give it a higher rating. Free coffee and front door man. The staff seemed tired and under appreciated.
