Concierge.com's insider take:
Once upon a time, the Principe di Savoia was Milan's number-one luxury hotel. These days, it has plenty of competition from several new kids on the block, among them the Four Seasons and the Park Hyatt, both of which are more centrally situated for the design and shopping action in the Quadrilatero d'Oro. But although it no longer wears the undisputed crown, the Principe, now under the wing of the Dorchester Collection, is still an attractive, classy five-star option that oozes old-fashioned charm—and it's still the hotel of choice for visiting aristocracy and political bigwigs. Many of the latter stay in the enormous Presidential Suite (almost 5,400 square feet), which features three bedrooms, a CCTV surveillance system, a Pompeii-style indoor pool, a Jacuzzi, a sauna, and a Turkish bath; but even below these giddy heights, rooms are opulent, with an abundance of rich fabrics, inlaid marquetry work, brass lamps, and crystal-drop chandeliers. We like the 48 new Mosaic Deluxe guest rooms, done out in a more contemporary idiom, with bright Mediterranean colors and decorative mosaic bathroom panels; however, some of the more traditional suites (such as the Napoleonic-style Elegant Suites) are also extremely desirable. The sheer size of this 401-room behemoth will not suit all, but it does guarantee top-class facilities, including a full-featured spa with indoor pool, a decent modern Italian restaurant, and two bars. It also means that rooms can be found at quiet times well below the official rack rates—online booking rates automatically adjust to reflect demand.
