My sister and I stayed at Torsten's beautiful apartment in Prenzlauerberg. The apartment is near both the S and U bahn stations making it very easy to get anywhere in Berlin. There is also a grocery store very close so we were able to use the very nice kitchen almost every evening. Amber was very accommodating and let us know that if we needed anything she would be available. I wouldn't hesitate staying here again next time I'm in Berlin!
