Andrea was very helpful and flexible in the organization of my stay at his place. The overall communication run very smooth and he replied each mail within minutes. I didn't get the chance to meet him personally but he arranged for the cleaning lady to way for me at the apartment at the time that suited me better.
The apartment is simply amazing: furnished with taste, it has a big living room, a completely furnished kitchen, two toilets and a very spacious bedroom. The area in which it is located is one of the most lively in Berlin with plenty of bars, restaurants and nice spots. I really felt like a real Berliner while staying at Andrea's place! I definitely recommend everybody to stay there!
