Great place: clean, with all the amenities one might need. Wonderful garden to relax in. Great location as well: near Ostkreuz that connects you to the entire Berlin. Wonderful SontagStrasse nearby - lots of awesome bars and restaurants to choose from.
Bianca provides a wonderful experience, one that is rarely seen nowadays at AirBnb where you actually meet a host, who is really renting you her own apartment. Wonderful communication, tips and atmosphere.
