"Check in was very slow as not many desks.
The room was lovely, the bar was very nice and had a big screen and seating area to watch World Cup games.
The room had air con which was lifesaver in the heat. The location was amazing, right by the DDR museum, museum island, close to train/underground stations, shops, cafes and bars.
Small warning- the still water at the bar restaurant is 9€!!"
