I really enjoyed my time in Berlin especially it was a pleasure for me to stay at Stefano's apartment which is very close to metro station. I liked its simple and stylish design, the apt was clean, warm and comfortable. Notwithstanding the fact I haven't seen Stefano, I am sure he is very attentive and polite person. I advice to stay in his apt if you like comfort and would like to have a nice place to stay in Berlin.
