Jetty and her sister Katja were seriously the best hosts one could hope for! They were friendly, generous and incredibly helpful which made me feel immediately at home. The apartment is spacious, clean and in a lovely safe neighbourhood with heaps of cool cafes, bars and shops. Its also very easy to get into Alexanderplatz, Mitte and has a direct tram to all the nightlife in Kreuzberg. I'd be back in a heartbeat :)
