This airbnb has an authentic italian flair. It's outside the typical touristy parts, but still in a nice walkable distance to the train station (to go to Pompeii or take the metro) and the old town! We also really enjoyed the balcony and the bottle of wine provided by our hosts ;)
The hosts are really invested in their guests: They can give you great recommendation for sightseeing and food (go to Oliva for Pizza, 5min walk, best pizza we've ever had)! The only thing that irritated us in the beginning were the many messages that we received from them: we weren't used to that from former airbnb hosts, but that is just their way of welcoming you and making sure that you're having a great time in Neapel :)
P.S.: For those wondering if you can hear airplanes since it's rather close to the airport: only rarely, I would say 2-3 flights/evening! It didn't bother us!
