This Tiber-side, 30-room, newcomer opened its doors in April 2016 with a number of choice amenities—a swimming pool in the verdant garden, for example, and an outpost of Paris hotspot Rasputin in the basement. Named after an 18th marquise, behind the almost stark white stone façade, the hotel elegantly mixes boudoir touches (velvet clad banquette seats in the bar L’ Autre Dame, one-of-a-kind chandeliers over white leather sofas) alongside more pared down features—consider the wood beamed ceilings and crisp white bedding set against custom headboards in green or dark blue fabric in the guestrooms. Huge windows and glass doors add to the light-filled environment. (Rooms from $395)
