We stayed here for 3 nights, and were very happy with the room. I was actually unwell for a day and spent a full day in the room, and it didn't feel claustiphobic at all. They had a Santa going around giving guest chocolates which was a nice touch. The location is good for Alexanderplatz, which had our favourite Christmas market. I can't comment on the food because we ate out, but we enjoyed the big beer hall which was a couple hundred metres down the road.
