Carolina is a great host; she answered all our questions within a few minutes. The flat is 5*, really, beautiful and has everything you need :) although the street doesnt look that nice, there is a private parking inside of the area and once you get a block or two away, the city is waiting for you. And to be honest, there are worse part of Napoli, although you might be surprised.. :D
Anyway, thanks again for everything and if we ever go back we will make sure to stay with you again :)
