The location is excellent for exploring Berlin with many sights easily reached by foot and others only needing a quick tram or train journey.
The flat is very comfortable and well equipped and despite its location close to transport, shops, restaurants and nightlife, it is very quiet at all times. Would thoroughly recommend as a base for a stay in Berlin.
We had issues with our flights to Berlin, resulting in a huge delay to our arrival. The hosts were very understanding and flexible around this.
