Grace Kelly honeymooned at this turn-of-the-century palace at the top of the Spanish Steps, and it's still the hotel of choice for many of today's celebs and stylish tastemakers in search of old-world elegance (Gwyneth, TomKat, and Victoria Beckham are all regulars). Renowned for its personalized service, the Hassler is a family affair a place where guest relations are taken very seriously. The 95 stately rooms are a checklist of classic good taste, with elaborate moldings, gilded furniture, French silks, 16th-century antiques, Limoges porcelain, playful frescoes, and marble, marble, marble, plus mod cons like flat-screen TV's. Imàgo, its modern Italian restaurant, has heart-stopping views of St. Peter's Basilica and Rome's terracotta-tiled roofs. And the concierges can accommodate just about any request, including mapping out routes through the Villa Borghese gardens, near the hotel.
Insider Tip: Learn everything there is to know about Barolos, Barbarescos, and Chiantis at the hotel's nearby wine school, founded by the Hassler's owner and general manager, Roberto E. Wirth.
