Davide's place is really in the centre of the old town. That said, be mindful that the Bellini piazza is a real place of party. If you want to be a part of the nightlife, then the place is ideal, because your "home" is right over there. We were traveling with a 10 month old baby and even for us the noise coming from the street was not a problem. It was like a smooth buzzing of the city.
Davide is fluent in English and really helpful with everything. We enjoyed our stay very much and hope to visit again in the future.
