DO NOT BOOK HERE. My group's reservation was cancelled DAY OF, actually, it was cancelled when it was time for us to check in and we were barricaded from even entering the property. 6 of us traveled hundreds of miles (not to mention 16+ weeks of training) for the Chicago Marathon, only to have our reservation cancelled the morning of our arrival.
I am not sure if there is a shady operation in place, but it is clear that AirBnB is not allowed in this building, as our group was escorted out and told "no AirBnb." The host's name also changed 3 times so I am not even completely sure who it is to address in this situation. I am completely shocked AirBnB is even allowing this space to continue to be listed to be rented.
Book anywhere else, if you value peace of mind in being able to count on having a reservation and a place to stay.
