Summary: Comfortable place in a good location, great spot for exploring Chicago.
Positives: Very clean, neat, comfortable. Nice location within the city, walking distance from fun stuff and also short train rides away from both the airport and downtown attractions. Host is very communicative, and even invited us over to dinner (but also totally gave us our space - the host gets an A+). We really enjoyed our stay.
Negatives: Not many negatives, it's a very good Airbnb. One thing is just the title; calling it an entire condominium is a teensy bit misleading. Picture an average hotel room, that's about how much space we had. More than enough for my girlfriend and I. It is pretty close to the train; we're New Yorkers so it doesn't bother us but people from more rural areas are going to need earplugs (which the host kindly leaves under the sink for you).
