Has anyone used the Leonardo Express to get from FCO to Rome city center? Our Air BnB is two blocks from the Flamino station and I thought to Leonardo express to Termini, switch to the city lines for 2 stops and whammo be at the apartment. I know the pickpockets are professionals in Rome, so that's in issue, I was wondering about the practicality of the train as an easier means of getting into town. Of course, the amount of luggage we're dragging will be a consideration...
