Both Carmen and John were extremely accommodating for our entire stay, they allowed us to arrive early and leave a little later as our flights were at weird times. As for the apartment itself, it was cute, homely and they even left some food basics out for us to use. Very thoughtful! The location is in a very cool neighborhood, I felt very safe walking around and it's super easy to get into downtown on the bus or L train. Would definitely stay here again next time we are in Chicago. Thanks for everything!
