The basic idea of Airbnb - or what it proclaims to be - is allowing for the chance to spend some time not in an anonymous place but with locals and learn a bit about the city with their eyes. Now of course that doesn't happen each and every time. But when it does it's great. Both my partner - who knew the city well already - and I enjoyed staying with Lucia in her apartment a lot: not only has she an amazing roof terrace in a great neighbourhood: she's also very hospitable, helpful and it's great to discuss with her. Also: great elderly neighbours downstairs, always willing to help in Napolitano :)
