This was just what I needed -- a cheap place to stay between O'Hare and downtown for a quick overnight. The place runs a bit like a youth hostel with private rooms. Each room in the house is rented separately with shared living and kitchen space.
Mary also has a person who she hires to hang around and keep an eye on the place. The system works well. The other guests and the person working there were all friendly but also respectful when I explained that I had a lot of work to do and could not really hang out. One note, the bed in this bedroom is very soft. My wife would love it, but it was tough on my bad back.
