We had a fantastic stay at Arzu and Tom's apartment. We met Tom on our arrival, he was very friendly and helpful. He told us lots of things to do and see in Berlin. The apartment itself is spacious, clean and has everything you need. Public transport is right around the corner and it takes just a few U- or S Bahn stops to go to the highlights of Berlin.
I'll definitely recommend this place and hope to stay here again sometime.
