I stayed with John for almost 3 months. The apartment is great and has everything you need for a long stay. The room and the whole apartment is actually bigger and nicer than it looks on the pictures.
The location is perfect. You can walk to all the sights in the loop, to the parks, the museums, lakefront, Navy Pier and the Riverwalk within a few minutes. A lot of cafes, bars, restaurants and shops are very close too. Public transportation stops are right outside the front door. I felt safe in the area all the time.
John is a wonderful, considerate and caring host. He was quiet, gave me space and privacy but he was also always happy to chat and open to do activities together like sports in the park or going to a bar. I enjoyed spending time with him very much and would definitely stay with him again when I visit Chicago in the future.
