Amazing place! Would highly recommend for anyone staying in Berlin.
The place completely fulfilled our expectations! The Tram stop just down the road made getting in and out of the center so easy as the trip was only 10-15 mins by tram to the city-center.
We had no problem with the tram noise as it was not overly frequent and from the bedroom we could not hear it at all.
Self Check in was nice and simple with the lock-box etc which is always appreciated.
Clean, tidy and everything you need from toilet - lounge - bedroom.
We even had an emergency issue which meant we were slightly late with our checking-out process but the people that represented the company were incredibly polite and understanding which we truly appreciated!
All in all 10/10 honestly, definitely would try to stay here again if we/I come back to Berlin.
