9 for a bottle of water . Air con broken in room and no opening windows meaning 3 extremely uncomfortably hot nights. Not a single room available to move me to apparently and no credit given on bill despite complaints last night. My colleague had the same issue in his room. Stains on the chair in the room and chipped furniture. Aside from a giant fishtank, this hotel has nothing going for it. I will definitely not be returning on my next trip to Berlin and it puts me off the Radisson blu brand.
