I had a great experience at this host location. The location is nice, fairly close to the loop and just a few blocks from the "L", with some decent restaurants nearby.
It is managed by a concierge service which has provided everything a hotel would and more - towels, soap and shampoo, etc. I especially appreciated the variety of plates, bowls, glasses, and utensils in the kitchen, which were quite helpful.
It's a basement unit and mostly quiet, although at times you could hear activity from above. The sound of the furnace was also kinda loud. It was very clean and elegantly furnished.
One thing that threw me at first was they require you to register on a third-party website and provide a selfie holding your ID. After some research and calling AirBnB I discovered that this is fairly common practice, and in fact Chicago law may require it. However I wasn't comfortable using the third party registration site as I couldn't find much information on it. The host compromised by letting me send a picture of my ID through the Airbnb chat.
The only con was, though the listing mentioned free parking nearby, I was unable to find any. It's possible that I missed it (it was dark and raining and I eventually gave up and used the parking garage across the street). It's also possible that this is generic wording used for Chicago by the concierge service and there isn't actually any free parking nearby.
However overall I am quite happy and impressed. 5/5 stars!
