According to Jaime Montilla, The Central Buena vista operated between 1882-1911 and was:

established at Barrio Hoyo Mulas of Carolina by Ignacio Arzuaga who installed a steam driven mill.  In 1882 equipment from the defunct Hacienda Monserrate in Rio Grande was installed elevating it to a central sugar mill.  It was later owned by the firm Sobrinos de Ezquiaga, established in San Juan in 1821 by Spaniard Jose Ignacio Ezquiaga (1775-1845) a native of Guipuzcoa in the Basque Country and a relative of Arzuaga.  In 1908 it was acquired mainly for its lands by the Loiza Sugar Co. who had recently acquired Central Canovanas.  For the 1912 grinding season, its mill was acquired by Cia. Azucarera de la Carolina whose major shareholder was also Sobrinos de Ezquiaga and installed at its Central Progreso.

Today, there are still ruins of the Central Buena Vista that are marked in google maps (see Google maps below) and that can be seen above ground (see Google images below):
