First of all, I'll have to mention the superb location of this hotel! 2 minutes walk from the subway, 3 minutes from KaDeWe (europes biggest department store), and basically placed at one end of one of Berlins major shopping streets.
The room was adequate, nice, and clean. The matresses were firm and very good quality. The toilet roll holder was for some reason located more than 1 meter from the toilet. Upon inspection, it turned out the shampoo dispencer in the shower contained hand soap. I'm sure this would have been an unpleasant surprise for someone with more sensitive hair than myself. Also, room service was done extremely early in the morning. The cleaning personal starting to knock on the door from around 9:00, even in the weekend. I visited during christmas, so one day I did not manage to leave the room before 10:00, and that day I missed the room service. We also had some problems with cigarette smoke leaking into the room (room 623), probably through the ventilation system. Very unpleasant when you're trying to go to sleep!
I never tried the hotel restaurant, as the menu did not inspire me. Visiting Berlin and Germany, I wanted to eat typical German food, and the menu did not meet that requirement. That said, it's a very nice looking place, and I'm sure the food is nice if you like the menu.
All in all, I'd say this hotel was good quality compared to the price!
