Concierge.com's insider take:
This 300-year-old palazzo opened as a hotel in 1911 and remains the swankiest place in town. Its Old World charm, marble lobby, and five-star service endear it to visiting dignitaries and celebrities. Each of the 109 spacious, individually decorated rooms is named after a famous Italian artist or performer. Plush drapes, brocade wallpaper, flowery prints, antique reproductions, and marble bathrooms give the accommodations an aristocratic swagger. Top-floor rooms are most popular and include small balconies, and all units are soundproofed to block out street noise. The hotel's ultraformal I Carracci restaurant is named after the famous Carracci brothers, whose 16th-century frescoes appear throughout the hotel: It's a favorite with expense-account businessmen and well-off local families gathered for dynastic Sunday lunches.
