Christine is a great host: she is very well organized and provided us with all the detailed information about the apartment days in advance before our trip. During the trip she was reachable at any time and answered promptly. She accomodated our request of having an extra set of keys in less than 24 hours.
She decorated the apartment in a very charming way and, especially with the sunlight, it is cozy and warm. Another good point is the location: very quiet and at just 15 min by bus from the loop.
The apartment and building have some flaws: first of all, as reported by others, the entrance, from the the rear door, and the stairs are stinky and not at all clean (cat pee?). However, I understand this is not under Christine's control. The electric system in the apartment does not seem very safe, e.g. many plugs to be fixed. Also note that the rooms, especially the bathroom, are small, so this is something to be aware of.
