If you want to discover the real Naples, this is the area you want to stay. It has a great market around the corner with fresh fish for really little money. Go for breakfast in the neighbourhood, ask for tickets for the game, and people will walk you to the 'Better' booth. Love it!
Via Toledo is around the corner. Look for the underground tunnels there, a great tour! Literally around the corner, take the train up for a great view of the city and visit the castle.
As for the apartment: it's clean and has several balconies with a good view. Quiet to sleep and nice spacious to relax. If you are looking for frying pans for eggs in the morning, check the stove. We found out after 2 days :)
Communication was great, as you will soon find out.
