We had a very short one-night stay at Posada del Chamán Iguazú on a trip to Iguazú Falls, with a flight arriving in the evening and planning a day on the Argentinian side of the falls before going to the Brazilian side of the falls the next day. The property is lovely, the rooms are clean, the hosts (Ramiro and his wife) couldn't have been nicer! The logistics of getting around the region and crossing the border hadn't been very clear to me while planning this trip, but Ramiro made it very easy! He picked is up from the airport to go to Posada, dropped us off at the Argentina park entrance the next day, arranged a time to meet at the entrance after the visit, then took us across the border, helped us understand and navigate the customs procedures, and dropped us off at our hotel on the Brazilian side. His rates for handling those transfers were very reasonable and it made our trip quite smooth. Would highly recommend Posada del Chamán Iguazú!
