The B&B is very nice, we enjoyed our stay there, the room was very clean and as described, the only thing, that would really play on your nerves, is the internet connection. The room in the first floor has very week connection, and you need to go up to the kitchen to get internet connection.
On the other hand, adriano is a very nice guy and he would help you to get to the best locations in Naples.
I would recommend it strongly.
