The Peninsula Hotel is renowned for its luxurious and elegant decor. The rooms typically feature high ceilings, plush furnishings, and opulent details. The decor style is a blend of traditional Chinese elements and contemporary luxury, with attention to detail in the choice of materials and design. The hotel's休息室 (rest room) would likely be adorned with exquisite artwork, plush fabrics, and perhaps traditional Chinese motifs, reflecting the hotel's overall aesthetic.
