Grand neoclassical gem on the Piazza della Repubblica, with a gigantic rooftop terrace, restaurant and pool Neoclassical grandeur. Housed in a dramatically curved 19th-century travertine edifice overlooking central Rome's circular Piazza della Repubblica, the Exedra welcomes guests through its front arcade and a pair of revolving doors. Inside, a soaring cream-colored lobby showcases intricate plaster moldings and a white grand piano. Up the brass-doored elevators, the 238 guestrooms are classically decorated in warm shades of brown, cream and gold; some of them are in a 15th-century annex, where exposed wooden ceiling beams and a terra-cotta-tile roof suggest its history as a papal granary.
