Lovely studio within minutes of walking distance from a public transportation station, about 30 minutes with public transportation to the hauptbahnhof and Potsdamer Platz. The sound of public transportation wasn't noticible in the studio.
If you're looking for a nice, small apartment and don't mind travelling for a bit this is the perfect place for you. Communication with the host was good and received very fast replies.
We had the option to have our sheets and towels replaced during our stay on request against a little compensation for the cleaner.
Only downside for my partner and I was the neigbourhood. It wasn't very inviting, but furthermore fine.
