[2] She grew up in her family's 12th-century castle, the Castello Sannazzaro di Giarole, in the Province of Alessandria.
[4][5] Her father inherited the castle in 1986, but the family did not move in until 2006, previously using it as a summer residence.
[2] After graduating, she moved to the United States, first to study theatre in Los Angeles, and then to New York City to attend the American Musical and Dramatic Academy, but returned to Italy during the COVID-19 pandemic.
[7][8] Sannazzaro started the account on 7 March 2021, during the pandemic, which impacted the booking of the family castle, which they run as a bed and breakfast.
