The Relais Guilia is where romantic dreams come true—complete with a canopy bed. Yet the furnishings in this historic palazzo never descend to gaudiness. Instead, they feature modern materials and furniture that blend effortlessly with the classic lines of the Renaissance building. Some rooms at this address on the charming Via Giulia look out over the rooftops of the neighboring buildings. The Relais only serves breakfast—a small but refined meal.
