Nice and simple. Location is great (literally the U-bahn metro station is around the corner), very closed to the Berlinische Galerie, shops, restaurants, etc. Hosts were very discreet and prepare my room very nicely. The house is very homely and very clean (there's always a nice scent around :). I really recommeded it for short and long stays. All of that for the price you pay is fantastic :) Will definetely go again if I have the chance to come back to Berlin.
