Rebecca is an extremely generous host and fun to be around! We went out to lunch together several times, and she also helped me get around the city. Her place is clean, comfortable and nicely decorated. The location is surrounded by parks, next to the University of Chicago, walking distance from bookstores, cafes, and a beach. Getting to downtown Chicago and connecting to the L is about 25 minutes by way of the number 6 bus which picks up right across the street. (Note that the Metra train stop right by the apartment is not the CTA and is its own system.)
I stayed for three weeks, and it was a cozy place to crash after traveling around the city or a quiet place to spend the day working. The bed is extremely comfortable too.
I had a great time and would definitely stay here again!
