It is not just a private residence. As it was mentioned in the clip, the offices of the Royal Household are located there, so it is also a working building.
I believe Zarzuela would be better described as a "Palacete" rather than a "Palacio" in Spanish. Juan Carlos had the choice of living in El Pardo, which is a proper palace, but he declined it, which I think was a correct decision at the time. Besides, the King can always use the Royal Palace of Madrid for more solemn events like state dinners, investitures and receiving the credentials of foreign diplomats.
Spain is not short of royal palaces, but, understandbly, it is in the interest of the SRF to look frugal.
