The hotel is in a great location - in the middle of it and yet quiet. Our room had a wonderful view of the Spree. For our needs, the bed was much too hard.
A big minus point gets the service! When we arrived at 11:30 clock we were told that the room was ready by 14:00 clock. Luckily we were on the way longer and arrived at 16:45 clock back at the hotel. Because we were put off again and finally had to wait until 17:15 to get to the room! That is not how it works!
In addition, the ladies and gentlemen at the front desk were usually very curt and not too friendly. Too bad - we would have expected more here.
