Roberto is a really thoughtful and nice host. Always ready to help or give recommendations. The place is spacious and clean with a nice view. The bathroom is quite small but ok. We didn't really end up using the kitchen (to much good food in Naples...) but it seemed complete and very usable.
While the location is really good, in a nice neighbourhood and close to public transit, it does take a while to get to the city center. Especially in the evening the transit is not very reliable, so be prepared to either walk a lot or take a taxi and spend a bit more.
All in all we had an amazing time in Naples and Roberto's apartment and we couldn't recommend him enough as a host!
