Arnd was very nice with us. The apartment had a lot a privacy with our own bathroom and preparation area with a refrigerator, was in a 4 floor and no elevator but he helped us with the luggage. The area was good and it was near the train station Berlin HBF. The wifi wasnt good, it connected and disconnected all the time. We were avaliabled to loundry our clothes and we used the kitchen with his permission, even that it was not includded in his service, so that was really nice of him. It was a very good experience, and it is a nice place to stay.
