Each room is advertised as being equipped with a desk/work station, presumably next to power and computer-related outlets. In my room, the desk was located on the wall opposite from the outlets, making the outlets effectively useless.
The bed wasn't very firm. There was only an undersized comforter, i.e., no blankets. There were an inadequate number of towels. The towels were cheap, i.e., very thin material. I had to adjust the rain shower head so that it wouldn't cause water to leak through the shower door on the bathroom floor. Also, I discovered that I had to line up the shower door just right so that water wouldn't leak on the bathroom floor.
There were no instructions for the heating/cooling unit. Some of the icons were indecipherable; fortunately, the room came w/an opening window. Perhaps, the healing/cooling control panel wasn't working correctly.
The breakfast plan was expensive (19E/day) and the food not very good. You are better off walking to the nearby Zoo S & U bahn station to buy breakfast at one of the surprisingly good German chain bakeries, e.g., Kamp's.
The hotel did not have appear to have a concierge.
Unfortunately, I was very disappointed. I would stay there again simply because it wasn't too expensive, is close to Zoo station, and has quiet rooms.
Location and very quiet rooms. Very close to Zoo station (U bahn, S bahn, and regional rail lines); Also close to shopping including the KaDeWe. As advertised, the rooms were very quiet. I heard no noise from adjacent rooms.
