My family (two adults and two children (ages 9 and 7)) visited Chicago and stayed in Beth's apartment for 4 days. It was perfect for our needs. While we had a car, we rarely used it (parking is easy/free). The neighborhood has lots of good restaurants and is about a 5 minute walk to a train station (with quick and easy access to the loop). There are also a number of good grocery stores (e.g., Whole Foods) within a 10 minute walk. The apartment was also comfortable/clean with modern/nice appliances.
We were very happy with our stay and would definitely stay again.
