They also owned the Manuelita sugar mill and the Compañía Azucarera Atlántica del Golfo, which was listed on the New York Stock Exchange. The family had links with the Fulgencio Batista regime. Some of the Monasterio family's properties were nationalised in the 1960s following the Cuban revolution, leading some of the family to immigrate to Spain.^{[6][7][n. 1]} Her father opened the first KFC in Spain.^[7]

Monasterio reportedly began studies in architecture at the Higher Technical School of Architecture of Madrid (ETSAM) in 1992.^[10] Monasterio and her architecture firm focused on acquiring properties and turning them into high-end lofts.^[11][12] She earned her degree in architecture in 2009 (the same year she joined the professional association of architects of Madrid [es]). This circumstance has led to the questioning of several plans and building certifications, she reportedly signed in the capacity of "facultative director" at least as back in time as 2003. The projects include partial demolitions for which she implicitly claimed to have the professional qualification which is condicio sine qua non to sign them off.^{[13][14][n. 2]}
