We had a lovely stay in one of the most gorgeous buildings in Berlin! The apartment is spacious, private, quiet, and the terrace deck is a real treat. Communication was very smooth. A few things could be improved such as issues with bathroom and shower drain (leaking and clogged), door from livingroom to terrace is semi-broken/cannot open, and the check in is a bit tricky to figure out how to actually open the door - make sure to watch the YouTube tutorial rather than read instructions. Although there is room to improve, I would certainly stay here again! :-)
