Kate and Rick's place is really lovely, clean, and comfortable. I do mean comfortable, the beds were great to sleep in and the place was very quiet. The place is decorated tastefully and minimally which we really appreciated, and the towels and bedding they provided were good quality. The TV was even set up with netflix which was awesome. Kate and Rick were really responsive as well. Our first night there we were in the middle of a show when the batteries in the remote control died. They brought us batteries within 20 minutes. Check in was painless and the location is amazing. It is right across the street from the train so you can come directly from O'Hare airport and not need a cab.
The only downside to the apartment is that it only has one entrance and the windows are glass blocks so there is no alternate way to get out in an emergency.
