To begin, Giovanni goes above and beyond for his guests. When I arrived, it was after scheduled check in time and he waited up for me, despite having to work the next day. He helped me with my bags, provided the change for the lift (10 cents Euro), and made me a traditional Italian Easter meal when I said I was hungry!
About the place:
Location/Accessibility: is very close to the train and bus station; about 5 mins by taxi. It is also walkable to these locations, but I was a single woman traveling after midnight, so I cannot speak to the duration. It is about a 20-30 min taxi ride to the airport, depending on traffic (will cost you about 13 euro; ask BEFORE getting in).
Cleanliness: Everything was nice, tidy and clean.
Amenities/Facilities: The shower is not one to spend awhile in as the water tends to get cold after about 10 minutes. To offset this, I just turned the water off and on while I was bathing and washing my hair. The bed is quite firm, but sleepable. The wifi was a tad spotty; I would not depend on it. There is a very low electric hum from the power that you'll be able to ignore while while you sleep.
As I said, there is a lift that will cost you a 10 cent euro coin. I was not aware that this bnb is an entire place inside an entire place (this was likely my fault for not reading). So be advised that there are several several rooms (places) on the same hall & yes, the walls are a bit thin.
Overall: This is a great value for the money and Giovanni is a superb host. I would definitely stay again.
Note: I was in Naples for the night only, so I can't speak to its location to food, attractions, etc. Hope this helps!
