Salvatore's place is a very basic accommodation.. a room in a good location for exploring (near via del Tribunali). The room opens right up to a relatively busy side street. There is no natural light expect for one small window. It is a good value. Very clean. The bathroom is adequate with great hot water, and there is a refrigerator.
Salvatore is the most responsive host I have ever come across at Airbnb.. an example to follow! He answers within seconds...
When I am back in Naples I would not hesitate to return.
The street can be noisy in the day, but at night I was able to rest uninterrupted.
