Vila Mimosa is not one, but a cluster of brothels in the downtown area. It is seedy, dirty, and cheap, but also very famous and well known. This place is frequented mostly by locals but if you are feeling adventurous have a look. For the most part you are not going to find the highest class girls here, but you will find some fairly attractive girls on occasion. The price to party and have sex with these girls is normally right around 50 Real ($20), and you might even be able to negotiate lower. Don't expect any of the girls to speak English here.
