Rainer was helpful and gave us clear directions so we could find the house easily. It is on a good location, very close to the Hermanstrasse station which is accessible by transport almost at all times. Grocery and convenience stores nearby as well. During the night however the neighbourhood gets kind of shady and there's pretty much nothing to do there.
The appartment is in great condition, cozy and gets plenty of light. It is a long climb though as it sits on the 5th floor with no elevator.
In general we had a fine stay and the location facilitated our going up and down in the city.
