Pros:
- Great location in the middle of the "historic" part of Naples.
- Elvira (the host) is very responsive, I never had to wait more then 5 minutes for a reply, even very late at night.
- House was quiet, at least during the night, I had no trouble with sleeping whatsoever.
Cons:
- Cleanliness (at least in my non-Italian standards) was far from perfect.
- Apartment is on the top floor, there's no elevator meaning a climb of 99 staircase every time.
- Bedroom's door serves as decoration, you can't close it, can be problematic in certain situations.
Overall had a great time there, I'd recommend it for young (and fit) guests :)
