Robert's loft is amazing, so spacious and brilliantly renovated. Robert is a fantastic host and whenever we needed some advice or directions he was ready to help us, offering also some detailed maps for every part of the city. His dog, Jack, is a sweetheart and is just lovely.
The spare bedroom has its own, huge floor with a private bathroom with floor heating, and the shower is simply amazing. There is also a "private" entrance on this floor, so you can enter the apartment without disturbing anyone.
The apartment is about 15 minutes by foot from the Hauptbanhof and 25 minutes from the Reichstag and the Brandeburg Gate. In a 10-minute-walk you can reach the Bellevue Schloss and catch the S-Bahn or the panoramic bus that crosses the city.
The apartment is on the 5th floor (4th if you use the service stairs and enter directly on your own floor) without the elevator, but the apartment itself is so wonderful you wouldn't mind, I promise!
