We stayed at Prenzlauer Berg for a long duration, 5 weeks, and it was wonderful. The apartment is exactly as described, very clean, spacious enough for 2 or 3 people for a longer period of time. We very much enjoyed the neighborhood, communication with Alex and Stefano was great, and couldn't have been more lucky with our find of this ground floor apartment. Price was very reasonable too. One small issue we had was with the noise level at times. The upstairs lady likes to exercise throughout the day "flashdance" style (sounds like quick running in place) and even after talking to her, she only turned it down a bit. And the side neighbors like to cook and listen to music around midnight a few times a week. Both are not terribly disturbing and with earplugs and time we got used to it. Overall, a wonderful experience.
