Axel, Valentin, and Antonin were incredibly hospitable and friendly and helped me make the most of a brief stay in Rio. They offered to take me to a neighborhood samba party and out with them, which was a great way to have a local carioca night I wouldn't have found on my own; Axel is really a great tour guide and gave me perfect directions for a two hour walking tour I was able to navigate on my own without difficulty. Great for a different way to see Rio than the norm.
