G-Andy, Naples has a flying club that may offer instruction. Access to the club is through the Italian Air Force Base on Via Doganella. I suspect that they are a very expensive operation.
Another possibility is at Capua Airport, about 15 nm N. of Naples. Access to Capua Airport is take the Capua exit off the A-1, go through the tollbooth and take a left toward Capua. The airport is on the right, and the access road is well marked.
Buona fortuna,
