I picked the 6-day jungle lodge. I was very excited about the trip, and the guide only made it better. He was very nice, funny, and has a very good knowledge of the Amazon. The river, the jungle, surviving, .... Samir is one of the most entertaining and learnful guides I've ever had, definitely recommended! If you do the tour, and he's your guide, you are in for a great experience! Besides that, his English was great! He explains everything in a very good way. 11/10
