I went to visit the Amazon River and I hired a guide called Marcelo Beniti who works in Amazon backpackers in the 10 de Julho hotel. I payed the trip in advanced since we had specified the details of the whole trip by e-mail before I flied. I have to say that first of all he switched the guide with a guy form a different company and the the whole trip plan was unfortunately a way different form the one I had hired. The is no way he gives me the money back only for the 2 days that I decided totally disapointed to come back to the city. be carefull with this kind of people in Manaus. Any similar experience???
