In the early 1930s, Cesare Spalletti Trivelli inherited the historic residence in downtown Rome from his mother where he would then live with his wife, Countess Guendalina Cavazzi della Somaglia. In 2004, Giangiacomo Spalletti Trivelli, son of Count Piero, and his wife, Susanna, daughter of horseback riding champion Raimondo d'Inzeo, decided to convert the family's historic residence into an exclusive luxury residence for the more refined and demanding travellers.
