Although we didn't meet the host in person we had regular exchange of emails. He was very helpful, responsive, and keen to know that every thing was ok for us.
The apartment is very nice, comfortable and spacious. We loved it and felt at home. The house is situated on a road that is quite busy during the week.
We were very happy to find basic stuff in the kitchen (such as drinks, milk, jam, oil, vinegar, tea...) . For those like us that don't bring their own car, it is important to know that the groceries are far from the apartment and not reachable on foot.
Public transportation is just one block from apartment and connects to the major places in Chicago. It is very easy to use.
We would definitively recommend this place to friends.
