I had a very cozy stay at this Sonder location. It's close to the L train which goes by every once in a while but after a day that sound is like white noise. If you're sensitive to that noise, request a room on the other side of the building opposite to the L train. The location is great. It's close to pretty much everything like shops, restaurants , the mall, and Millennium Park just a few blocks from Lake Michigan. The location is only a 5-8 minute walk from the blue line that goes directly to Chicago O'Hare. I enjoyed my stay and hope to be back soon.
