Fairly quick replies, late check-in possibility, quite a nice room considering the overnight fee and the elevator are some of the things that made our city break/concert travel in Berlin a lot easier. The bed in the room was a tad short in length but the mattress, pillow and duvet were perfect. Very close to the underground U7, which goes to the city center and to and from the BER airport. A lot of shops and bakeries to get breakfast in the area as well.
