Daniela was extremely accommodating in arranging for us to collect keys from a friend who lived nearby, leaving a list of cafes/bars/restaurants and responded to all to my queries promptly. The flat was better than I had expected - extremely spacious and comfortable for a couple or two people, and conveniently located less than a minute away from the U-Bahn. I also highly recommend the area Friedrichshain for cafes, bars, restaurants, and discovering little shops and secondhand stores. All in all, we had a great stay at Daniela's apartment!
