Even though we only stayed for one day/night, Salvio was an exceptional host. He provided us with a huge amount of really useful information about Naples (and the surrounding area) and made himself available earlier than expected at short notice to check us in personally (including with some freshly baked sfogliotelle which was a nice surprise!).
The flat is in a great location (10 mins walk to the middle of the historic district) and is clean, secure and fully equipped with everything you need (including wifi).
Overall, we would highly recommend Salvio's place and we would definitely stay here again.
