We spent four nights at Yearn's apartment during Berlin film festival, right in the middle of easy-going Prenzlauer Berg with its nice houses and its numerous eating and drinking places, and less than 10 minutes to the nearest U-Bahn and S-Bahn stations. The apartment is spacious and comfortable, and gives in a big inner courtyard shared with other houses. The design is quite original, though sometimes a bit dysfunctional :p The communication with Yearn also went very smoothly. All in all it was a gorgeous stay in one of Berlin's coolest places and I'd be very happy to stay there again and finish my restaurant tour :D
