From Fiumicino Airport take the direct train to Termini Station. It runs every half hour and takes 30 minutes. The first morning train goes at 6:37 AM and the last evening train at 11:37 PM. (If you arrive after 11 PM it is best to take a taxi to the hotel, the cost should be about 45 Euro). At Termini station take the right exit straight you find via marghera then first right via magenta 24.
