Great location (next to the Ost train station), and lovely flat. We have not seen much of Christine during our stay, but she seems like a lovely person. The place was very clean and the bathroom very fancy.
Some small things that may bother you depending on what kind of sleeper you are: there were no curtains in the bedroom, and the bed consists of two single mattresses (with quite a hard but low divider in the middle) and two single doonas. We didn't mind all of this, but you may.
