Rita is the most welcoming and hospitable host. The apartment is right off a U-Bahn stop and somewhat central, which is convenient. One thing to note is that it is not hidden away in some tiny neighborhood smack dab in the middle of coffeeshops...you'll need to travel a bit for that. However definitely safe and quiet. Apartment itself is a cool, typical Berlin (high ceilings, great light, big windows, spacious) place.
