Me and my wife really enjoyed staying with Cherilyn and Walter. The location was safe and quiet (must be beautiful in warm seasons), with lots of street parking, close to big grocery stores and only 6 minutes away driving from McCormick convention center and 10-12 minutes from downtown Chicago.
Cherilyn and Walter have an adorable small dog and a sweet older cat, who we loved spending time with. Both hosts work a lot, so we did not communicate every day, but whenever we had time to talk, they both were very caring and nice people.
You will get a clean cozy private room with your own bathroom, which is an amazing deal in Chicago, but you need to know there are stairs to get there (this wasn't a problem for us). There is a cleaning lady who comes every week, who changed our sheets and cleaned the room (we stayed for more than a week). You will be able to use the kitchen and the fridge. The hosts always had bottled water for us, too.
Overall, we had a great time, and no complaints at all. We highly recommend staying with Cherilyn and Walter, and would love to book their place again if we come back to Chicago.
