I can't thank enough Marco (and his flatmate Chiara) for the hospitality and all the help they gave me during my stay in Berlin. The apartment is very close to important U- and S-Bahn stations and to bus stops, from which you can get pretty much anywhere in the city easily. It's also a very cozy place, with a great atmosphere in a nice neighborhood that's both calm and bohemian. Really hope to meet you guys - and Berlin as well - again!
