This is a seriously glamorous hotel, right in the heart of the city. Shades are almost mandatory and designer labels are never out of place, even at breakfast.
Come here after a spring or summer wedding, because the draw of this grande dame is the exquisite Secret Garden, scented with jasmine and orange trees, where you dine alfresco in Le Jardin de Russie restaurant or sip Campari and soda at the Stravinskij bar.
There's a fabulous spa (naturally) with hydropool and Turkish steam room to relax in after a day eating gelato on the Spanish Steps or posing by the Trevi Fountain, both of which are within easy walking distance.
WOW FACTOR: For what's hot in Rome right now, ask the hotel's hilarious and very charming concierges. They'll give you handwritten VIP passes to the best clubs and bars in town.
GO: Seasons (seasons.co.uk) offers four nights B&B in an Executive Double from £1,095 per person. Includes flights and transfers.
