The day I arrived at the flat, Ulf had fruit, water, and a list of information waiting for me in my room. Everything was as described in the ad; the room was even more spacious than expected! Either Ulf or Alberto came by often (at least once a day) to keep the common areas tidy and ensure that we had everything we needed/wanted. The kitchen was particularly nice, because it was very well-equipped with everything you'd need if you felt like cooking. The location was also a huge plus, because a major tram line stops at Marienburger Str./Hufelandstr. (which takes you directly to both Alexanderplatz and Hackescher Markt).

Both Ulf and Alberto were so welcoming, helpful, and understanding! It was, overall, an excellent experience staying at the flat! I'd recommend it to anyone looking for a centrally-located place to stay in Berlin.
