We stayed here for 5 nights and found it a great hotel to stay in. The rooms and bathrooms were clean, the beds were comfortable, it was a quiet location. There is an underground train stop about 30 metres from the door, linking you with everywhere in Berlin. The cafe/restaurant had tasty food and a small bar. There is the option of using a kitchen downstairs too, which could save money if you're there for any length of time! Also a games room with a TV. Internet is available at a price, and there is wifi in the lobby (not sure about the rooms!). As the temperature was -13c on at least one occasion, the heating must have worked well too as we were never cold!
