We had a lovely month-long stay in Michelle's apartment. It is very conveniently located for anything you could wish to do in Berlin. Right by a tram line that takes you to Alexanderplatz in 5-10 minutes (but without any tram noise in the apartment). It is close to the very pleasant Volkspark Friedrichschain, and all of Prenzlauer Berg is just a short walk or bike away. The apartment faces a back courtyard, and is *very* quiet at night, which is a real plus in Berlin. The apartment itself is clean, comfortable and spacious, and we would definitely stay there again.
