Un desastre, iba arriba adelante sin cinturón, se llovía por la ventana, sin wifi, paraban donde querían, el trato de los choferes para responder hostil, no había agua en el baño, nos llevaron a un taller sin explicación, y no nos dejaban bajar, todo el viaje subiendo y bajando gente de otras unidades que se rompían, tengo fotos de todo. No recomiendo un viaje a distancia con esta empresa, muchísimo mejor JBl, una vergüenza tener que explicar a los Brasileros que viajaban que Argentina no es asi, que crucero del norte no nos representa, horrible experiencia!!! Gracias a la gente amable que viajaba se hizo más llevadero!
