I visited Villa Borghese back in December 2012. We had landed in Rome earlier in the day and this was our first excursion into the city. Rick Steves offers an introduction to Villa Borghese in Rome: Baroque Brilliance.

I had already booked tickets online. Had no problems getting tickets, and the museum was not crowded at all. While waiting for our designated time, we explored the park grounds.
Villa Borghese was the perfect introduction to Rome—a small museum that can be easily explored in a couple hours. Despite its size, it is filled to the walls (and ceilings) with paintings and sculptures.
