We were four nights at Damiano's. The room was clean and comfortable for two persons. Damiano was so nice host and we felt like at home. The apartment is situated 5 minutes by walk to the archeological museum and in 10 minutes you are in via Toledo, so we can say is well situated. Also, the neighborhood is nice because is like a typical Naples one.
As a negative points, only to say that the apartment is a 4th without elevator (which I think is quite common there) and I wouldn't recommend for people who hate smoking inside. We don't have any problem with smoking and the elevator, so we had a perfect stay there.
I recommend the place!
