We had a very nice stay. It was on a second floor of a big house, we had a lot of space to stay, and the fact that it was not in the city center (downtown) didn't matter because it was near to a couple of stations of the L system (Chicago's elevated subway). It was very calm at night, but there was also a nice atmosphere in the neighbourhood and things to do (and eat!)
We didn't get the chance to meet Jonathan but was always available and very kind.
We would definitely recommend it.
