Everything was exactly as advertised. We did not get to meet Matthias but he left very clear instructions as well as loads of information and tips for touring. The location is near perfect for touring. It is close to public transportation and the main railway station, although, for the moment the M5 tram is a bus due to construction. The apartment is modern and well appointed and we loved hanging out on the balcony in the evening. We would certainly stay here again when in Berlin. There are tons of things here for every taste and I feel as though we bars scratched the surface.
