Escape the hustle and bustle of Rome and wander over to the Galleria Borghese, a lovely art museum in the Villa Borghese. Since the museum contains both sculptures and paintings, you are bound to find one piece to your liking. Masterpieces include Caravaggio's 'Jerome,' Bernini's 'Apollo and Daphne,' Titian's 'Sacred and Profane Love' as well as Raphael's 'Disposition'.
Although our guidebooks said it was difficult to get in without a reservation, we did not have problems getting tickets. Admission is timed and you are allowed in for 90 minutes-- probably not quite enough time to do it justice. Depending on where you are from, you might be able to get a student discount. Americans don't qualify though.
After visiting the museum, be sure to stroll around the villa. It makes for a great picnic spot and is a nice retreat from the crowds.
