Meio Mundo is really a nice brothel cum sauna. The boys are much fresher and varied inthan the better situated Clube 117. It is big, clean and not expensive. Just pick your boy (or refuse those who try to grab you, if you are not interested). Most of them are versatile and all of them are 200% clean. Don't hesitate to be clear to say what you want. The fee for the boys is around 100 reais (more or less 50 euros) + the admission and the cabin. They give you a codom and the lube.
Meo Mundo in Centro is a very nice locals sauna with rent boys. Locals, rent boys, 2 level sauna, food, drinks, clean, take cab to and from (not good area at night). Very hot local boys according to visitors!
