Staying at Christoph's was comfortable and made easy by quick and efficient communication. The other occupants we met were friendly and respectful, everybody was careful not to disturb one another.
You can easily get to the city centre by bus or tram.
As a constructive point, the bathroom door does not close easily as it runs against the frame. Pushing too hard risks it slamming, perhaps this could be adjusted. The bunk bed was a bit creaky, but perfectly comfortable nonetheless.
