good communication with Hannah, flexibility in terms of late check-in due to delayed plane, quiet, U-Bahn and supermarkets nearby and also a swimming pool with sauna too (closed for renovation when I was there). There is a big towel for the sauna, kitchen is well equipped, a washing machine, and a table usable as a workplace. The electrical heating needs a bit of foresight; it cannot be regulated and when both panel ovens are on, it gets too warm. For me it worked best to leave the one in the hallway on when cool outside and the other off. Nice place, it has charme, and I consider booking again.
