We really enjoyed staying at John's place for the weekend! The condo is very well decorated, spacious, and very homey. John was super responsive throughout the weekend; he answered all of my questions very promptly and gave us some great local recommendations. There were 5 of us staying: 2 in each of the 2 bedrooms, and 1 on the air mattress he set up in the living room. Everything was perfectly set up when we arrived and the beds were very comfortable. The location was very convenient for us (we stuck around Foster beach) and we felt safe walking around in the evening. John helped us locate some paid parking lots in the area (~2 blocks walk) in case we couldn't find street parking - it was about $20/day for one vehicle.
Note: It was trash day on Saturday morning and the condo is on the first floor, so it was a little noisy in one of the bedrooms (Paris-themed one) and the living room. Not a huge deal, but if you're a light sleeper and want to sleep in on a Saturday I would recommend having some earplugs handy.
Overall, we had an excellent stay and would highly recommend John's place to a group looking for a chill comfortable weekend in Chicago!
