We stayed at Tracy's for a few days during the Chicago Marathon weekend.
Overall, we really appreciated the welcoming atmosphere and her kindness. She was always available to help us out with any questions or requests we had. That made quite the difference.
The accommodation is descent but the room where we stayed was rather small. The majority of the space was taken by the twin size bunk beds so there wasn't really enough room for our suitcases. I think other rooms were more comfortable so make sure you clarify which room you are getting.
