Staying at Lois' flat was perfect.
I spent one month and a half working in Burr Ridge, so Oak Park was the best position at all. Both my job place and Chicago city were easily to reach in roughly 30/45 minutes by car.
The house is big and very cozy. Nothing was missing at all. There is one clean and quite comfortable bathroom (the unique downside, if I must say: there is only one bathroom), one huge room and two other pretty rooms.
Lois was too much sweet. She made us a Thanksgiving cake and the Christmas tree! Very kind of her. She was always available and ready to answer our messages.
