Great location. The metro and most of Berlin's attractions are nearby.
The hotel has a large number of conference rooms. Be careful with the room cards. If you put it in your pocket with your phone, it will immediately discharge. The hotel corresponds to its network.
I stayed for a day at this hotel, they charged me 300 euros for an absolutely standard room. Problems with hot water, but generally clean. The bed is comfortable, it is clear that the hotel is old
