What can I say, first of all Killian is very kind and a nice person to talking with! She gave us advises on what to do to enjoy Chicago.
At the house you have plenty of privacy (you'll have your own way in and your own bathroom).The house it's placed a bit far from downtown Chicago, but the area it's very well served with public transportation. To go to the lake it's a very short walk. There's a very nice place, nearby, to have breakfast called kitchen sink. Killian has two cats, one is very shy so you'll probably never see it, the other one is pretty cuddly, so enjoy it's purr!
We had a very good time, killian is a very good host!
