We stayed at Frank's place over the Christmas holidays. Not having visited Berlin in the winter, our initial impression was grey. But Frank's home was warmth and coziness! It is a quiet, residential neighbourhood that is conveniently located, close to restaurants and grocery stores. The big shopping street (Ku'Damm), Kaiser Wilhelm Church & Christmas Market, and the Berlin Zoo were all a 15-25 walk away. There is a Ubahn station 2 blocks away. Frank's apartment had everything we needed - from cozy robes to a full kitchen where we did cook a couple of meals. The tv is hooked up to Netflix (which the kids loved when we needed a lazy day) and we could even print our boarding passes for our next flight from the printer. It was a home away from home. If we needed anything, Frank was available by phone. We wouldn't hesitate to stay here again. Thanks, Frank!
