The communication is excellent with Markus, the location is very good, only a 20min walk to Alexandraplz, and there are some excellent bars and eateries around the area. There is a metro/tram nearby. The smaller bunk bed is too noisy (as others have said). We didn't cook, just used the kettle, but all you need to cook seems to be there. Enjoyable stay and I would recommend staying there.
