Jorn's place is a very charming, small apartment, clean and cozy, with everything you might need during your stay in Berlin. The metro line U9 is just in front of the building and is well connected to the other transportation lines in the city. Jorn was very quick in answering all our questions prior to our arrival and very warm in welcoming us. He also gave us some interesting tips on the restaurants in the neighborhood and things to do around.
