Planning on proposing? This ivy-covered palace, just off Piazza Navona, is an ideal choice for a special-occasion stay, with luxurious rooms, enthusiastic staff, and a roof terrace with spectacular views across Rome. It’s a gorgeous hotel, highlighted by 20th-century artwork inside, including Picasso ceramics and paintings by Mirò, Morandi, and De Chirico scattered across the property. The standard rooms are all decorated in Victorian style, with antique furnishings and hardwood floors. Some prefer staying in the Richard Meier–designed executive suites, which blend modern and Asian design and feature oak paneling, contemporary art, and Carrara marble. A haute organic, vegetarian restaurant will leave even diehard carnivores sated.
