If you’re someone in ASU for the first time and looking for a good local guide to show you around the city a bit, I recommend Felix. You can contact him directly via WhatsApp +595 983 786316
He’s a proper dude. He’s travelled halfway around the world with the circus and speaks French and a bit of Russian as well as English, but I haven’t tested him. He knows the city very well and besides the favela he will show you around depending on what you are interested in
