I was visiting Berlin last month and after some research, decided to stay at Ritz Berlin. Excellent choice, too bad it was just a brief visit. Although I was in Club level and the the lounge was under renovation, the alternative was excellent; it was on the lobby but nothing to complain about. My suite was a corner, excellent view, although you don't expect that on Tiergarten. Centrally located, excellent service, good food, complete. I highly recommend and definetely would stay again.
