I have the good fortune to meet a EXTREMELY nice taxi driver whom I left my iPhone in.
He not only found my phone for me, but also drove out of his way to my apartment to return it.
I have been in Rio for a long time and this is the best and most honest taxi driver I have ever met.
This really enforce my faith in my fellow man.
His name is Aluizio. Number is (21) 983723798.
