Lena's apartment was a great base for our 5 days in Berlin. It was safe, warm and very peaceful. The furniture was very stylish and the location was perfect for cafes, restaurants and bars. Transport links were a particularly strong point, enabling us to get to most parts of the city quickly using the metro and trams. The Wifi was the strongest we have experienced so far in Germany. Prenzlauer Berg remains an interesting place to walk around discover new squares and parks.
