I stayed in this apartment for two weeks, and it was an incredibly positive experience. Annette was always at reach, she checked me in and made me feel at home from the beginning. The apartment itself is a VERY comfortable one, amazing bed, fine bathroom, reliable internet, and well equipped kitchen, in a super special area of Kreusberg, the Graefekiez, slightly removed from the more crazed clubbing area (but of course still at walking distance from it). It was pretty perfect, I would never hesitate to stay here again or to recommend it to a friend.
