What is the color of luxury? Subtle sage, muted gold and rich mahogany brown. Its sound? Soft music in the background, muffled footsteps in the distance and rustling silk. The smell of luxury? Freshly cut flowers, lustrous polished furniture and scented soap. The taste? Hot coffee, warm pastries and chilled champagne. And the feel? Plush velvet, smooth satin and textured damask. All of your five senses will be awakened in the Carlo IV. Its 150 splendid rooms, designed by architect Maurizio Papiri, are the epitome of genteel elegance. Advanced technology and fine amenities are the additional luxuries that make the Carlo IV the preferred address for the discerning traveler.
