A great space -- everyone really enjoyed the rooms and the decor. There were lots of creative little touches to make us feel at home, including a fun instructions writeup.
The neighborhood is very hip. There was a great little coffee shop a block away. Public transportation was easy to access, and it didn't take too long to get into central Berlin.
Matthias was very fast to respond to our questions and key exchange was painless.
We really enjoyed the apartment and the neighborhood. Would definitely stay here again.
