I would highly suggest you google map the address and go to street view before booking to make sure this is a place you want to stay. (If I could upload a picture for you I would...) The pictures of the apartment were not representative of the area.
The apartment is as pictured (and is clearly renovated in an old building) however the neighborhood was not what we were expecting. We did not feel safe and while things were within "walking" distance it was not in an area we wanted to or felt comfortable walking around in - especially at night. Having never been to Naples we were unfamiliar with the area.
After checking in, we chose not to stay here and were not given any refund - even for the cleaning fee (even though we didn't even stay one night). I understand that we could have researched the neighborhood better, but I was disappointed in the response from Fabio. I would caution against staying here unless you are from Naples and know the area. Overall a disappointing (and costly) Airbnb experience. Hope you can learn from us!
