We had an amazing time staying in Berlin and in Kirstins apartment. Kirstin was not in the city when we arrived but her friend Marlene welcomed us in a really great way, gave us instructions how to travel around the city and which places to visit. Communication with both Kirstin and Marlene was fantastic. The apartment was super clean, fresh, cozy and very comfortable to stay in. There are two tram stops very close to the apartment so it's very easy to travel to other parts of the city. I can easily recommended Kirsrins flat if you want to visit Berlin.
