I stayed over a weekend in Hendrik's apartment in Prenzlauer Berg, and I absolutely enjoyed every bit of the experience. The apartment's location is great! Just in walking distance from many restaurants, cafes and small shops. The apartment was very clean and comfortable, and Hendrik even left a little guest booklet with recommendations of places to go/eat and practical advice. Very handy! I addition, Hendrik was flexible with the check-out, and let us leave our luggage for the day. Hendrik was also at all times very informative and super quick to respond to email. I can definitely recommend Hendrik's place:-)
