"I experienced a grand old dame near Palazzo Barberini with 161 gilded rooms that channel palatial glamour—powder-blue and terra-cotta hues, restored Venetian chandeliers, and hand-engraved mirrors. Bathrooms feature Marquina black marble tubs and Bottega Veneta toiletries, while impromptu performances by the St. Regis Rome Orchestra and bespoke butler-led Rome Experience tours add memorable, old-world touches." - Maresa Manara
