My father and I enjoyed a great stay at Soren's and would highly recommend the flat. Whilst a little out of the way it's easy to get to both the airport and the city center using the available public transport. The flat itself is a good size with some very comfortable beds, perfect after a long day sight seeing. Communication with Soren was simple and easy and he was always very responsive to our questions. Definitely recommend staying with Soren and wouldn't hesitate to stay again if in Berlin.
