Actually, I would have to give zero stars for the return transport from our Hotel San Martin to Foz do Iguazú Airport, because at 3:25 a.m. at the agreed time, the assigned driver did not appear. But since the overly friendly and helpful driver of the outward transfer left us his cell phone number just in case, we were able to contact him at short notice. It was he who reacted quickly and drove all nine people to the airport on time. As far as he is concerned, the full score and thanks for the quick and uncomplicated action. Since it was probably a misunderstanding within the agency, sponge over it and my full recommendation!
