Excellent. no other words required. We spend a very long and joyful day with Francis, in this tour to the Iguazu Falls we stretched the time more than ever. At all time Francis was offering alternate routes to get the best views possible, and with enough time to appreciate this magnificent place from both sides (Argentina and Brazil). Francis receive a big thank you, Gracias, Obrigado. We appreciated your company during our visit to Foz de Iguazu. I would definitely recommend Francis as a guide.
