I also read somewhere São Paulo ranks in the top 10 most expensive cities in the world. But that's clearly not my experience. The hotel park republica I stayed in, at 50 us$ a night (closet, huge bathroom, large terrace, decent mattress) beats the 72$ a night 'cheap' love hotel (no closet, futon mattress for action, not sleep) in centro rio hands down! There are also tons of shops and restaurants at very reasonable prices in SP, about 50% more expensive in RIO. For example, there are many sit down quick meal restaurants around park republic, about 10R for either some brazil dish or pseudo Japanese. Around gloria, where I am staying now, similar plate runs into 20R, in centro, difficult to find a restaurant where you feel comfortable walking in not speaking their language.
Lurker, If you are into twinks as your posts suggests, you are really missing out not hitting SP. give it a try next time! Coming from Canada, I have to say Iguacu beats niagara hands down, just as Sauna wise, Lagoa puts MM and 117 to shame. The only western standard sauna among the three, both facility and staff, very professional.
