My wife and I plus our two adult sons stayed here for a week and we were all very pleased with the apartment and its amenities. The apartment itself is very spacious with two large sitting areas.....one at the front of the house and the other as part of the kitchen. The kitchen was modern and very well equipped. One of the big pluses in the apartment is the fact that there are 3 bathrooms. The showers were powerful and hot. The two main bedrooms are large with good sized beds. The other two bedrooms are smaller but suitable for comfortable single use.
The apartment is situated in a quiet neighbourhood and access from the street is straightforward and secure. It is easy to find and check in was very easy. Although there is no station in the immediate vicinity there are bus routes within a few minutes walk. I would recommend the purchase of a 3 day or weekly pass for train and bus. That means it is is very easy to combine bus and train to travel into the city. During our stay we used a variety of routes and found them all simple to use.
Communication with the host was good and he replied promptly to the couple of questions I had.
In summary I would highly recommend this apartment and would certainly use it again if visiting Chicago
