Hailed one of the world's finest villas for couples by Condé Nast Traveller, this historic tower sits within a modern glass pavilion looking out onto unspoiled Tuscan countryside. Swim in the oxygen-cleaned infinity pool nestled in an olive grove (complete with countercurrent machine), clink glasses in the hot tub with exquisite views, lounge in the steam room, cook alfresco under a pergola or explore nearby Siena, less than 15 minutes away by car.
