My fiance and I stayed with Francesco for 2 nights on a week long Italy trip.
We were very impressed with the size of the room and the furnishings, it was air conditioned too!
It was a little noisy but closing the shutters helped a lot. Our host spoke little English, but was warm and friendly and made a nice breakfast. The place is close to nice restaurants including the famous Pizzaria Da Michele and not too far from the train station. A good bnb to stay at in Naples!
