We arrived when there was a shuttle waiting to depart but the queue was very long and we could not go on this bus. The wait was nearly half an hour for another to arrive. Whilst the trip in was good, in future I would take the train, both end up at Rome Terminal station.
My Wife and I had a Terrific trip to Rome to watch Scotland Play Italy at Rugby, the trip was really smooth from the Flights to the Bus Transfer to the Novodomus Hotel, Rome , staff at the Hotel were excellent and room was lovely only a stones throw from the Vatican.
Easy to use, was able to scout some of Rome before arriving at Termini. This is an excellent option if you're staying anywhere near Piazza del Republica. Bus was clean, had wifi, and only took about 45 minutes in heavy traffic.
