We stayed 3 nights with Franziska. Arrived in Berlin in the morning and it was no problem to drop off our luggage, which was convenient as we could go back to the city and enjoy the day. Right outside the door the Tram runs with regular stops only a short trip from Berlin Main station. Also a great bakery right outside the door. A few steps away are restaurants and bars which is also convenient. Very close to Berlin Wall memorial also, walking distance from Nord Bahnhof also.
Franziska and her daugther are very friendly and openminded and we enjoyed coffee in the morning (which Franziska prepared for us :) - thanks for that) and had a friendly talk before we left for the city. Both Franziska and her daughter gave suggestions to what to see and where to eat. The place is very quiet and you hardly notice, that Franziska and her daughter are also in the apartment. You have your own private room and bathroom too.
All our best recommandations to Franziska - we will be happy to return whenever in Berlin again.
