Aibonito (Spanish pronunciation: [ajβoˈnito]) is a small mountain town and municipality in Puerto Rico located in the Sierra de Cayey mountain range, north of Salinas; south of Barranquitas and Comerío; east of Coamo; and west of Cidra, and Cayey. Aibonito is spread over 8 barrios and Aibonito Pueblo (the downtown area and the administrative center of the city). It is part of the San Juan-Caguas-Guaynabo Metropolitan Statistical Area. Aibonito is located at a relatively high elevation (its main square is the highest in the island at 732 metres (2,401 ft) above sea level), which makes its climate cooler than most of Puerto Rico's towns.

Villa Julita, also known as Casa Ulrich, is a private building in Aibonito, Puerto Rico which is on the National Register of Historic Places. Currently in good condition and located at its original site, it was designed by architect Alfredo Wiechers Pieretti and built by Salvador Lando, in 1915, for the Vendrell-Suárez family. The architect who was a native of Ponce, had studied in Paris, and won a gold medal for his achievements in 1905. He graduated in 1905 and worked in Barcelona with Eric Sangier until 1911. Villa Julita is a mansion built of wood with some of its facade in concrete: the colonnade, the stairway and the balustrade. These elements give it a neoclassical look to what is a Creole style structure, following in the tradition of haciendas and summer houses of the time. In 1917, the residence was sold to the Wirshing Serrallés family.In 1950, the Ulrich Foundation allowed it to host conscientious objectors of the wars of Korea and Vietnam. The Mennonite Foundation bought the property in 1972 and used this land to carry out instruction and guidance to farmers. The Mennonites are responsible for introducing modern methods for the mass production of fruits and plants, as well as artificial insemination techniques for livestock.Harry Nussbaum and Linda Ulrich, the current owners purchased it in 1974 and spent four years restoring it.It is now a children's preschool. Villa Julita maintains its elegance and serves as a testimony to a time when Aibonito was a favorite summer holiday for well-to-do families.
