The location of the hotel is perfect for visiting museums and many main sights of Berlin. These are just a short walk away while hotel itself is on a very quiet street. Good quality hotel, clean, everything worked, good minibar (which was offered free if one abstained from room service), adequate space, good wifi, good toiletries, nice looking appearance, no disturbig sounds reached into guest room from outside or other rooms. The few drawbacks were: bed was a bit too hard, reception of international cable channel froze sometimes (problem might not be something hotel can do anything about), the blanket was too warm.
I would recommend hotel and stay again.
