We stayed one week in Berlin and were really happy in Sven’s place. The location is really convenient, we bought a six-days ticket for public transport and used underground daily, there are a few stops of different lines nearby. The house was clean and full of lovely details: we really liked the decorations on the walls. We traveled with our 5 year old son and the house was very good for him too. He was so happy to find an activity book on Berlin to color! We had dinners at home, the house has everything you need, included dishwasher tables and washing machine powder!
Really really reccomended!
