The following TripReport snippet is taken from 2004/07 LAguy's Mini Casa Trip Report: R$1/2 per minute

It should be mentioned that the casas on the list are rated according to cost, with $$$ being the most expensive. I had not yet committed to going the R$1/2 per minute route, so my first stop was Al. dos Jurupis, 1408, rated at $$$. The place actually had a nice interior, as casas go, with a couple of rooms to lounge in and a bar. Despite the $$$ designation, it was reasonably inexpensive: R$35 per half hour and R$60 per hour. However, there were about four men lounging around, and at first only one available garota. She introduced herself and while her looks were reasonably good, I got a "less than friendly" vibe from her. After a few minutes, another garota introduced herself, and I was considering a session with her, when the mama-san asked another hombre who he wanted and he picked her. While the first two garotas I saw were passable, another two came in the front door, apparently reporting for work, who were not. I decided to leave, although I probably will check out the place again. As with many casas, the garotas who are not immediately available are often the most desirable, so unless you stick around for awhile, you may not see the best talent. This time I didn't have the patience to stick around.

To get to Al. dos Jurupis, 1408, all you need to do is go out the back entrance of Shopping Ibirapuera, and make a left on Al. dos Jurupis. It is about one block down on the left. While I am not sure about this, I believe they are only open weekdays, unlike many of the other casas in Sao Paulo that are open six, or even sometimes seven days a week.

Well, I still was being taunted with "Me So Horny" and needed to regroup. I noted in the past I have tried a few of the cheaper places, and have sometimes found diamonds in the rough at these places, often resulting in great sessions. I saw on my list a couple of $ rated places and decided to check them out, notwithstanding that I knew the accomodations would leave something to be desired (but would likely be substantially better than at the R$1 per minute places in Rio, which it turned out they were).
