stayed with 5 friends, beds were super comfortable, the location is excellent and they answered and questions and concerns we had quickly. they allowed us to arrive early to drop our luggage off!
top tip: when you arrive, you can get the M4/M5 tram from alexanderplatz to practically outside the Airbnb.
only negative was that some of the doors had to be forced to close, other than that it was an amazing airbnb in a great location, would definitely stay there again if I returned to Berlin
