Barbara und Alessandro have a nice little Bistro with organic vegetarian food (It´s delicious!) and marvellous coffee. The room is clean, cosy, and equipped with nice vintage furniture and with a private bathroom. Barbara made a list of places you should spend a visit when you are in Berlin and she also helped me out with questions about the public transport. I had a realy good time staying at their place in Berlin and i will definitely stay here again.
