This small hotel is tucked down a medieval lane, on the edge of Monti, with the forums of several Roman emperors as neighbors. Rooms are tastefully luxurious, with colorful silks, soothing tones, and spacious bathrooms. The posh fifth-floor Master Garden Rooms have private patios surrounded by flowers and greenery, ochre walls, and busts of emperors, and a plush apartment with a kitchen sleeps up to six people. The hotel’s roof lounge has views of the Campidoglio, and for archaeology buffs there’s an ancient Roman cryptoporticus behind the lobby. The inn isn’t cheap, but the views alone more than make up for it.
