nice and easy
Landed there several time with a C650 and 8 pax. yes it is short but no obstacles. absolutelly better than Naples, they do not want you there, fuelling and passenger handlings are really a mess! in LIRI is nice and easy, no traffic and friendly handling. do not expect a lot services availability (no catering, no bar at the terminal...) check fuel availabity.
If you are staying there ovn there is the Pizzeria of the world award winner in the old part of the city. "Pulcinella" or other name like this.
have fun
