A really nice place to stay. A good-sized studio with a nice, separate, kitchen. Quality furniture and appealing, subtle, decor. The immediate neighborhood is fine; go a little further (by bus, in the winter; I'm sure you could walk in the summer/spring) and you're in exciting Neukolln, or hip Kreuzberg (note, however, that the name of the neighborhood is a little misleading - Kreuzkoelln is not so much *between* Kreuzberg and Neukolln as adjacent to both; check a map to make sure the place is central enough for you). Going to Mitte for the sights (museums etc.) takes a bit longer - bus or bus-to-train - but is definitely doable.
