My girlfriend and I stayed at Karen's apartment for two nights.
Everything was perfectly organized. We picked up the keys at a take-out restaurant close by and at the apartment found a welcome letter with description of sights in the area and general description of the neighborhood and a map on the table.

The apartment was as described - quiet, bright, clean and spacious for two (except for the bathroom, which is rather small).

We felt very welcomed and would stay here again any time.
