I realize a lifetime isn't long enough to see all of Rome, but reality is that we only have 4 days to see the following:
Day 1: HOHO bus tour, Spanish Steps, Trevi fountain
Day 2: Guided tour of Vatican Museum, Sistine Chapel, St Peter's Bascilla and St. Peters Square
Day 4: Santa Maria Trastevere area, Campo de Fiore, Via Appia Antica road
Is this doable in 4 days or should we seeif we could squeek out a 5th day?
