We enjoyed our stay at Martina's place. The location of the apartment is perfect. Prenzlauer Berg is a beautiful neighbourhood with a lot of bars, coffee places and small shops. Connection to the rest of Berlin is easy via metro and tram. Communication with Martina was super. We could just pick up the keys and leave in in the apartment after departure. To all questions she answered directly. The apartment is nice and with two bedrooms very suitable for two couples, four friends or a family. However it is a rather practical place which has all functional things you need for your stay, but it's not too cozy. It was a bit cold since Berlin autumn can be cold already and the heater is turned of centrally and ok-clean. It's a very nice place if you want to explore Berlin, but it does not invite you to spend a lot of time there on a rainy day or for a cook-at-home dinner.
