Once the private apartment of Phillip of Wurttemberg, the 160 to 500-square-meter or 1,720 to 5,380-square-foot Royal Suite features silk upholstered walls and glittering crystal chandeliers hanging from seven-meter-high, stucco-decorated ceilings. Fashioned in the manner of the Schonbrunn Palace, these suites include a grand living area bathed in natural light and occupy the entire front of the Hotel Imperial's belle stage. Authentic nuances come from antique porcelain ovens and star-patterned parquet floors that have been preserved and carefully restored, and now house a wardrobe, six-person dining area, and multiple sitting areas. Padded double folding doors open into the spacious master bedroom and salon. Three additional connecting rooms with respective bathrooms may be added. The marble master bathroom with soaking bathtub, shower, and double vanities presents a soothing end-of-the-day sanctuary supplemented by exclusive Bulgari bath amenities.
