I will be traveling from Chieti to Rome by train and would like to spend a day in Tivoli on the way. I figured out how to do this, but need a place to leave my luggage in Tivoli while I am sightseeing. Any ideas?
There are left luggage facilities at both Roma Termini and Roma Tiburtina... so either works, depending on where you arrive from Chieti. Here's an article with more info on the "luggage storage" options in Italy: Left Luggage Facilities
