My friends from the USA Joe and Derek and myself from Barcelona rented Stefanie´s 2 bedroom flat in the neighbourhood of Schoneberg in Berlin for 4 nights in March. The apartment is brand new, beautifully designed, high ceilings, huge bedrooms, 2 bathrooms, really nice industrial design, totally our taste. It is the biggest airbnb apartment I have ever stayed in any city. On top of that, it was in a great location, in a street with restaurants, well communicated by public transportation and very quite, so sleeping at night was a pleasure. We had welcoming water and beers, as well as a nice music system that we could connect to our iphones.
Stefanie is very friendly and was there to greet us as well as for our farewell, very helpful with all sorts of information about Berlin and very fast to respond. Also, the apartment is located next to a Youth hostel , so the people at the reception are familiar with Stefanie in case you need extra help (leaving luggage, keys or even buying snacks ir drinks).

We couldn't stay in a a better apartment in Berlin, I would definitely recommend it to anyone and staying at Stefanie´s flat in Berlin made our visit a superb trip.
