Guarulhos is a city in São Paulo, located in the metropolitan area of the city of São Paulo. Despite being a metropolis with 1.2 million people, Guarulhos is mostly known for its international airport, the most important of South America and the main gateway to São Paulo. Indeed, as an industrial city, Guarulhos has not much to offer to a visitor, although there are remarkable exceptions, like the Cabuçu center of Parque Estadual da Cantareira, one of the most beautiful nature spots of the São Paulo metropolitan area.
If your reason for considering staying the night in Guarulhos is that you are heading back to the airport the next day, you will not be much worse off choosing accommodation near Praça da República, downtown Sao Paulo, to which there are frequent direct buses from the airport.
