Our stay at Arnd's was great. The room is exactly like the photos show and very clean. Arnd was a really nice host, kind and helpful, he helped us to plan our way to the airpport ro avoid closed lines due to construction, we wouldn't have made it in time without his help. In addition to this, on an unusualy hot day he made sure we were confortable. The apartment is in a great area, safe to walk around and very near to Berlin Hauptbahnhof wich has great links to almost everu where in the city. Great experience, I highly recomend it.
