Venetian furniture, vintage glass light fixtures, and a marriage of silk and woven fabrics fill the room with a historic Italian ambiance. The headboard combines arches and sharp edges, a nod to the country's Renaissance castles.Similarly, the Budapest suite features Gothic and Ottoman architectural styles, with ornate marquetry and embroidered silk-patterned furniture. The tall, curved headboard recalls the cathedrals and mosques of the Ottoman Empire.
