We initially viewed the Villa Farnesina on our first trip to Rome. We had about an hour. Later we lived in Rome for six weeks, very, very close to the villa, and went back twice more for a total of 6 hours. If you are a fan of Raphael, you must visit this place; the frescoes are vivid and rich with detail. If you are not a big fresco fan or Raphael lover, you can probably get by without this stop, but it is magnificent nonetheless.
