Our house is in a nice old residential area, between public transport and three different natural reserve areas, perfect for hiking, biking, kajaking etc. The stadion that was built for the Olympic Games in 1936 but is still in use is less than 1 km away, with sporting areas all around it.
Other sites in that radius are a Cold War American spy station on top of the "devil mountain", our local hill with a lovely view over Berlin and the forests around it, the "Waldbühne", an outdoor concert location (Rolling Sones etc.) built into a little canyon and the "Glockenturm", a tower with a view that is part of the Olympic Park.
In 5 minutes by bike or one busstop you can get to the Havel, a river that widens into a lake (Wannsee), where you can swim or do all kinds of water sports, or simply sit on a restaurant ship. Another lovely lake to swim in (Teufelssee) is situated in the forest (Grunewald) and is just as close.
Our two direct neighbours are very friendly families.
