Feito was born and primarily grew up in Madrid, with a four-year stint in Paris. She attended a British school in the former and an American school in the latter. She said she "clung" to English during her time in Paris, as she had a better grasp of it than she did of French. She was also interested in English literature from a young age, particularly The Secret Garden, Roald Dahl, the Brontë sisters and Charles Dickens. Feito graduated with a Bachelor of Arts (BA) in English and Drama from Queen Mary, University of London.
