You should stay here if you go to Naples. It is in the heart of the old town, walking distance to most the places that everyone was going to, metro or bus ride away if not. Metro is 15 minutes on foot east or west from the apartment, man-made beach is a 30 minute walk or a metro ride away. 5 out of the 6 best pizza places in Naples (or the World) are within 30 minutes of the apartment on foot, 3 of them (Michelle, Trianon and Port) are only 10 minutes away.
The apartment is straight out of a catalogue, clean and tidy. Everything is brand new and, unlike some places, all the small bits are there too: extra virgin olive oil, coffee, a couple of beers for you when you get there, cutlery, washing liquid, etc.
Fabio couldn't be nicer or more willing to help, he was on WhatsApp whenever we needed him and was a mine of information about a city that he obviously loves and lives in.
Stay here, it's great..
