James was very nice and helpful ! He could not be here to give us the keys when we arrived but he left them at a nearby shop and it was just as easy as in person. The flat was perfectly clean and functional. The room itself has a comfortable bed and it's heated (which was essential as it was quite cold). The neighbourhood is also really nice with a number of good restaurants and bars. Furthermore, the flat is well situated as it is near a large S-bahn station that connects to the center of Berlin as well as to its suburbs and neighbouring towns.
Overall would recommend !
