Our host was waiting for us at the apartment when we arrived and was very welcoming and helpful in getting us situated, as it was our first visit to Berlin.
Overall it was a nice, comfortable apartment in a great location with shops, parks, restaurants and transportation nearby. And yet the street we were in was so quiet and leafy we couldn't believe how quiet it was at night outside our windows.
The apartment was lacking in a proper living room/sitting area, however the kitchen/dining area was more than sufficient for our small group to gather at night and it was comfortable.
