We had a great time at Osvaldo's apartment. It was very well located near the centre of Napoli. The apartment was quite large and spacious with a very comfortable bed and extremely fast internet. We stayed there on a Saturday night and it was a bit rowdy outside with late night revellers but staying that close to the centre it was too be expected (you can't have everything)
Osvaldo was also very quick to respond to our queries and we would definitely stay there again.
