Even if the location of this hotel is perfect, straight on Alexanderplatz, you can immediately spot it as one of the leftovers from the Soviet times! It is the archetype of the big ugly tower. In the meantime, the hotel has been successfully refurbished and the interior looks much better! I suspect the view from some rooms on 30+th floor could be quite nice but I was on the 10th floor and the view was nothing spectacular!
The room itself is quite small and, quite surprising, the bathroom is directly integrated within the room. Even if there is a separated toilet, the shower is made of transparent glass. That's a detail to take into account if you plan to share your room with a friend or a co-worker!! However it was nicely furnished with a modern touch and the bed was quite comfortable.
I haven't tried the wired Internet connection from the room but I didn't manage to get the wireless connection working from the room and I had to connect from the lobby where it was working fine with iPass.
