Housed in a separate, chalet-style building a short walk from the main castle, the 66sq m Spa Suite is a stylish and secluded retreat designed to inspire forget-the-world relaxation. Striking and modern in design, the suite has teak-clad interiors and floor-to-ceiling windows that look out across the Ombrone valley and river below. It has its own hammam, sauna and a wooden ‘barile’ hot tub, positioned on the sun deck to catch the Tuscan sunset. There’s a king-size bed with luxurious Italian bedlinen, antique furnishings and two ensuite bathrooms – one with a walk-in shower, and a second, teak-walled rainfall shower in the hammam area. The suite also has free WiFi and a smart system that lets you call for a butler 24 hours a day.
