The sign on the corner building says "Padaria e Mercearia," which is Portuguese, strongly indicating Brazil. The dense overhead power lines and the specific style of the urban architecture are very characteristic of Brazilian cities. The yellow taxi/car and the general street layout further support a location in a major Brazilian metropolitan area. I am fairly confident this is in Brazil, likely in a city like São Paulo or Rio de Janeiro.

The street sign clearly reads "Rua Laura de Araújo" and "Rua Santa Maria." The area code (21) on the banner is specific to Rio de Janeiro, Brazil. The architecture and dense urban environment confirm this is a neighborhood in Rio. I am very sure this is in Rio de Janeiro, Brazil.
