We enjoyed our stay at Leo & Alex place. The location and the parking were the most valuable benefit as we were right outside downtown, only 15 min in car. Other than that the place was great for a group of 4. The area is pretty quiet, with few restaurants, a bakery and a supermarket around the corner. It is a great deal to visit Chicago!
Only note: as many have mentioned it in previous comments, sound travels really easy and you can hear the people from the upstairs apartment.
