This is a simply wonderful unit -- aesthetically pleasing, well equipped, and mercifully tranquil despite its wonderful central location. Yes, the four flights of stairs take their toll. But don't let that deter you from renting this very sweet apartment. Verda manages it with the perfect touch, and you will find yourself in a wonderful neighborhood of Berlin with easy access to everything the city has to offer. And still able to have a very good night's sleep (I am a very very light sleeper -- and was able to leave the bedroom windows open at night -- a real joy!)
