Short story: I recommend this apartment strongly for large groups or families. The AirBnB ad is truthful and Hans and Helen are experienced, competent hosts. Read on for details.

Hans and Helen have an efficient operation established with their apartment. We never met in person, but they provided (and I much appreciated) clear instructions and contact numbers. They also communicated well with us before the final booking went through, never leading us on or misrepresenting the situation (as we were booking for New Year's Eve, we were not first in line :-)).

The apartment is everything promised by the ad. Clean; comfortable beds; fixtures, appliances, and climate control in good working order; pictures in the ad are accurate. In addition, Hans and Helen provided soap and shampoo in the bathrooms, a hair dryer, towels, and plenty of extra linens and an air mattress. Hans responded promptly to my e-mails about not being able to find the towels. :-)

The location is in (what I gather is) a gentrifying area, so guests have the benefit of new and exciting bars and restaurants, but not the drawbacks of rampant tourists and crowding on the streets. There is a lot of free parking nearby, as well as connection to the Chicago El system. El transit time to the Loop is something like 10 minutes, including waiting in the station.

The apartment is pricey, but when you consider that it sleeps 10, it becomes an attractive option for large groups or families visiting Chicago for whatever reason. It's exactly what I wanted out of AirBnB: more space and better location than a hotel for a cheaper price. I've stayed in approximately 10 AirBnBs in the last decade and would rank this one in the top 3.
