Leo's apartment is exactly as described. It's clean to the point of being shiny. The beds are comfortable, the lounge a great place to relax and the kitchen is well-equipped with everything you need as well as spacious. It's located in a quiet residential street only a few moments walk from restaurants and shops and a not too far from the Blue Line. In terms of safety, we walked to and from the station a few times at night and didn't feel in any danger.
I would return to Leo's apartment again when in Chicago and recommend to all who need a comfortable base.
