Rome is a very attractive city. But I can say that Davide's favor was more impressive than any other site, such as the Colosseo. His house was as clean as the picture, his breakfast was fantastic, and he always looked after his guests with great care. During I was staying in his house, I really felt like my house was in Rome. I will miss Rome, and I will miss his house even more.
If you are going to visit Rome, do not hesitate to stay in his house. He will welcome you like a best friend.
