We spent one night, but would have been happy to spend more time. Rosario is an excellent host. The accommodation was spotless and comfortable with lots of Neapolitan charm. It is situated inside a former convent. Parking was not easy, and is on par with general driving in Naples-but if you brave Naples driving you can manage. The convent is located up a staired alley so does require a walk and climb from the parking -if you travel Naples on foot, the climb is small. We felt very safe in the neighborhood returning after dark. The bedroom window cuts out 100% light so for those who are looking to get a good nights sleep without interruption to overcome jet-lag, this worked for us.
The kitchen area is very small, but well stocked with a good stove and oven. We prefer to visit the local restaurants but did make coffee in the morning with a provided espresso pot over the stove- much appreciated.
