The location of the apartment is really good, close to a very cool area of Berlin and 3 tram stations away from Alexanderplatz (or max 15 minutes walking). It can accommodate a large group of people which is nice and the host is really friendly and quick to reply. The cleanliness level would need improvement but it's not so troublesome if you just need a place to sleep in and in the rest of the time you'd go visiting around.
