One of Rome's ritziest resorts, the Rome Cavalieri is a hilltop oasis far from the hustle and bustle of the centro storico, with magnificent views, an Olympic-size pool, and a palatial spa. Perched atop the Monte Mario amid 15 acres of lush Mediterranean parkland, the resort, formerly a Hilton but now owned by Waldorf-Astoria, offers complimentary shuttle service to get you to the city center. Guest rooms (ask for one facing the city) are spacious, with striped damask, puffy armchairs, and no shortage of luxe amenities, including the Waldorf-Astoria's "pillow menu." Many have large balconies. The icing on the cake is La Pergola, the hotel's rooftop restaurant, which is renowned as one of Rome's very best, with three Michelin stars.
