It was a nice hotel. Very busy due to lots of conferences and there were really long queues at reception. Room was nice, great shower, bed comfy and all very clean. There wasn't enough tea and coffee and it didn't get refilled when the room was cleaned. Good location with the U-bahn and trams nearby. The spa isn't part of the hotel, it is a business next door and guests get a discount. We didn't get a chance to go though as there was so much to see in Berlin. Overall, pleased with the hotel, it is quite pricey for what it is, but I would stay there again I think.
