We stayed in the apartment for two weeks in july, and it was a good experience overall.
The location in Prenzlauer Berg is very good with a lot of nice places to eat and hang out and cosy streets to walk. It is super accessible with trams and s-bahns making every part of Berlin reachable within 30 mins!
The host was easy to get in touch with and made fast replies to questions.
The apartment is a classic small Airbnb apartment with one room and a great balcony (bigger than the room). The cleanliness could’ve been a bit better (e. g service, the balcony floor was in some places broken and had lots of algaes, the bathroom drain was clogged).
