La Grande Bellezza Rooftop at Eitch Borromini
Rome has no shortage of gorgeous rooftop terrace bars open in the warmer months, but this one—nestled amid cupolas and bell towers atop the Eitch Borromini hotel—is exceptional. Seats along the edge look down on Bernini's famed fountain in Piazza Navona. The chic white couches are almost always filled with well-heeled Romans, making sunset reservations essential.
