The apartment is in a great location if you're travelling via Schönefeld Airport. The Berlin Subway is only a few minutes walk away which we found extremely useful. We went to a gig at the Columbia Halle which again, isn't far away from the apartment. There are numerous places to eat nearby, and also supermarkets.
The apartment is clean and warm (it was very cold when we visited!). It has a great shower, basic cooking facilities, dining room table and is very cosy.
Lena was flexible with check in/check out times which helped us greatly, and she was quick at responding.
Would definitely recommend this apartment, and stay here again. Thank you!
