Alexander was an excellent host. Communications and instruction before my arrival were clear and to the point. A family member graciously waited for me, let me in and showed me around at my arrival. The apartment is very spacious and super comfy, right next to a tram stop and near all the cool and fun places that Prenzlauer Berg has to offer. Throughout my stay Alexander communicated regularly and was always willing to help make my stay comfortable. There was a minor issue with the internet and he did his best to resolve it (it was not necessary in the end since it seemed to be a temporary problem). I highly recommend Alexander and his apartment.
