Great find.
We'd never heard of the Club Quarters before arranging a one night visit to Chicago in July 2012. Excellent location right across from the Chicago Riverwalk - right across the river from the Trump Towers. Easy walk to get to the "tourist" areas. Great value compared to surrounding hotels. The room was smaller than a lot of hotels, but it really just cut out the wasted areas. Bathroom was clean and had a nice shower. Only complaints are that the card keys either didn't work or took a dozen swipes to get to work - an experience echoed by others we talked to in the elevators; and they only provided one hand towel for two guests - again a complaint shared by others we talked to. The front desk people promised to get more to us, but never did. Overall though, I'd stay there again.
