We stayed in Simone's place for three days. The space was great for us, as a family of four with grown up kids. Simone's husband, Guy, was there to meet us when we arrived quite late, and explained how everything worked. The flat was spotless and all exactly as described.
It was really easy to travel to all the different parts of Berlin we wanted to visit from the flat, by underground, bus or tram.
The area itself is pretty quiet, and not the most lively, with a few bars and shops nearby, but easy to get to busier parts of town.
Simone was really helpful, answering all my questions before we arrived and during the stay.
