I recommend from the bottom of my heart! Karen is a very communicative and cheerful person. She advised us how to get to the center of Berlin and told us about interesting places in the city. From the neighborhood where the house is located it is about 20 minutes by train to the center of Berlin and 20 minutes to Potsdam. The place where we slept was very atmospheric and you could feel at home there. The room is stocked with everything you need. If you forget a towel or razor you don't have to worry because you can find everything there. Thank you very much Karen for your hospitality. We hope to see you again!
