We booked this apartment for our stay for the Berlin Marathon. The space was quiet and the neighborhood was safe at night. There are a ton of restaurants just a short block or two away and a wonderful farmers market on Saturdays.
The space was a little off the beaten path as far as trying to get back and forth to the Tiergarten for runs, but certainly not impossible. The Berlin Marathon runs within a couple of blocks of the apartment, so as a spectator, i was able to see my runner, then head back to the apartment to recharge phones or whatever, then head back to the train station and grab another quick look for my runner and then go straight to the finish line before they finished.
The amenities were perfect for our needs. Jörg was so nice and we appreciated his suggestions of places to eat the first night.
