I know Rick Steves prefers San Callisto over San Sebastiano, by just a hair (he basically says either will give visitors their catacombs fix). He even says of San Callisto, "These are my favorite catacombs..."
Can I get the opinions of other people who have been there? I'm curious why both Rick Steves and Fodor's seem to completely ignore the Catacombs of San Domitilla? Steves even talks about the Catacombs of Priscilla in his book, but not San Domitilla. Yet, Frommer's says San Domitilla is the best of all. Weird...
So, what do you guys think? Also, how does exploring the Appian Way (maybe a picnic, a bike ride along the ancient road, seeing the Tomb of Cecilia Metella, the Villa and Circus of Maxentius, and one of the three catacombs) compare to a day trip to Tivoli (seeing Villa D'Este and Hadrian's Villa)? Thanks.
