I really enjoyed my stay here - it was only one night of my trip and I wished I had booked it for longer. I had a river view room, and it was probably one of my favorite hotel rooms and views I have ever had. The hotel staff was very helpful (and spoke excellent English as my German is lacking). The bed was comfortable, curtains blocked light well, and it was very quiet. My only confusion was that the master switch for the electricity was a big red switch on the wall that I was afraid might be an alarm of some sort (it was not). Great location, and a lovely river walk right along the river steps from the hotel. I also did eat breakfast here, and although a bit pricey it was a great buffet with tons of options to choose from, and you could eat outside as well. I would definitely stay here again if I find myself back in Berlin.
