Carsten was a excellent host, he was extremely helpful and informative. The apartment is in a lovely quiet location in what appears to be a good neighbourhood. Nearby travel and shopping amenities are excellent. The apartment itself is well equipped and we had a very comfortable and enjoyable stay. Although we were aware of the number of them in advance, the only minor negative we could highlight, is the number of stairs from street level up to the apartment, however, if we were to visit Berlin again, we would not hesitate to book Carsten's place again. Its a great place to stay and we would thoroughly recommend it.
