Great flat, centrally located and close to the train station (Hauptbahnhof). Quiet, nice atmosphere in the neighbourhood and also the flat itself. If you don't mind a bit of improvisation (shower in kitchen, bed in living room) this is a good place for 4 people. In any case, we had a good time. However, it is good to realise that in the event of stricter Covid measures in Germany, there is no possibility of a refund.
