Excellent location if you prefer peace and quiet. Herbert, the host, is superb in responding and very helpful.
The neighborhood is super nice! Those visiting Freie Universität will particularly like this location.
If you like to stay fit, their are several swimming pools(e.g. Hüttenweg or Finkensteinallee) that you can run to in 15 minutes and Grunewald is easy to get to for serious running.
Lichterfelde station, a 10 minute walk away, is surrounded by many restaurants as well as an excellent Biergarten next door. This station is also fastest way into central Berlin.
