We stayed @Jonathan's place in the beginning of June and we liked it a lot. the flat looks exactly like on the photos. we could find everything we needed, even some food/drinks and my favorite: hair dryer. as we came from Europe, my devices for the bathroom didn't have much power with the adaptor so I really appreciated it.
Jonathan was a very nice host, he tried to help with everything. at the beginning it was a little bit cold in the apartment so we told him and he turned off the whole AC system for us.
Chicago downtown is not far, by car it took us 15 min.
there are several restaurants, pubs in the neighborhood and a huge Target 5 min away by car as well.
it's a really nice place, we recommend it for everybody visiting Chicago.
thanks for everything Jonathan!
