Great apartment, plenty of space for 2 or 4 people sharing. it's quite central and within walking distance to the sights of Naples. the outside patio is lovely as well!
The only issue I would highlight is the noise,coming from within the building(the apartment is right next to the main door for the block of apartments which doesnt seem to close quietly) and there were parties going on while we were staying, which made it difficult to go to sleep. This I suspect can be resolved by bringing earplugs, if you are a light sleeper!
