Reception
Bernard P. E Bentley deemed the film to be "a showcase for its large cast". In the view of Jordi Costa, it is one of the Spanish cinema's great jewels to be discovered. Joaquín de Luna considered the film to be a "little-known" instance of Hispanic costumbrismo featuring the "refreshing" intervention of Gracita Morales. According to Jordi Batlle Caminal the film belongs to the "insubstantial" subset of films within Sáenz de Heredia's filmography.
