Historic hamlet with 14 apartments, swimming pool and striking Roman bath in a cave for sale in Monteriggioni. In the heart of the Sienese countryside, located in one of the most exclusive and sought-after areas of Tuscany, the property dominates an exceptional hilly landscape, offering a breathtaking view that stretches to the famous towers of San Gimignano and the medieval profile of Monteriggioni. The property is easily reached via a typical paved panoramic country lane, which guarantees maximum privacy while remaining a short distance from the main services and road junctions. The complex, skilfully restored in authentic Tuscan "arte povera" style and with the most modern sustainability standards, consists of a main building in stone and brick housing 7 apartments, as well as a large restaurant with bar, professional kitchen, pantry and wine cellar. Adjacent is the charming manor farmhouse, elegantly divided into two large mirrored, interconnecting residential units. The property is completed by two separate outbuildings: the first houses two large exclusive suites with unique panoramic windows, while the second contains a further 4 independent apartments. A note of absolute prestige is the underground Roman Bath, an exclusive space carved into a natural cave with water heated to 38°C. The hamlet is surrounded by a meticulously maintained park-garden equipped with a children's play area and enriched by a splendid outdoor swimming pool with sun terrace. The entire green area is served by a rainwater collection system optimized for automatic irrigation. The estate extends over approximately 3 hectares of private land, including a productive in-ground olive grove with about 150 olive trees, plus three separate outdoor parking areas for a total of 40 parking spaces. A perfect property for investors wishing to acquire a high-profile hospitality business already generating income, or for those seeking an exclusive prestige residence in the heart of Tuscany, with the possibility of converting the entire complex into a prestigious private multi-family residence.
