I was here for a week and it was excellent. The hotel is centrally located and has great bars behind it, as well as great restaurants and coffee shops around. It is adjacent to the Brandenburg gate and the Jewish Memorial. There is an awesome night club near the hotel (50m from the back entrance) with cheap entrance (5 Euro). There are always taxi's available. There is free wifi available and the service is excellent. During the time I was there, the president of Singapore had also been staying here.
All in all a great stay!
