Subject: Baggage storage in Rome

My son is leaving in August for a semester to study in Rome. He wants to leave a few weeks early and do some traveling on his own. He can't check into his living quarters until the end of August. I was wondering if anyone knows if there is reliable baggage storage available to stash his big suitcase as he would be unable to travel with that. Any ideas or suggestions would be greatly appreciated.
