I've already replied to your email, Silvaire1, thanks much for getting in touch directly!
Handling is truly the issue at airports in Italy, not so much landing fees which are just a few euros, a few euros too many in any case!
Some handlers try to play dumb and charge for services which have neither been asked for nor performed. Trust me when I tell you that I've toilet cleaning service charged on a Piper single engine piston!
The good news is that some aviosuperfici are now equipped with 100LL pumps, recently Terni (northeast of Rome) has added automatic pumps for 100LL, Mogas and Jet A1, so any type of aircraft can be fueled. And Terni is a former airport with a 3000' asphalt runway turned into aviosuperficie, to avoid the mess with bureaucracy. Sometimes ingenuity gives the right answers...
Ciao, Luca
