Clean and comfortable room. Conveniently located near U-Bahn station. Staffs were very friendly and helpful.
Service elevator use in the morning a bit cumbersome, since it tends to be utilized by the service staff. I suggest using the other elevators in the morning (a sign guiding that would have been nice).
Breakfast on the expensive side, but little choice with not many delis/ convenience stores in the neighborhood (I also think there were no refrigerators in the room). A 2 tier breakfast plan (cold breakfast at cheaper price in addition to 18 EUR full breakfast) might have been nice..
