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.

Overall satisfied with our 3 day weekend getaway. Hotel is very close to shopping and things to do and see in Chicago! Very friendly staff and my favorite part the shower, lol! Although you can hear your neighbors when they are talking only when you sit by the couch!
