7 hours in São Paulo

No, it's not but there's a metro stop there, so you can take the metro from Tietê. Rodoviária is simply the word for bus station. Personally I'd just take a taxi to where I wanted to go.

Thanks corisco. What colour line is Tietê metro station on? I can't find it on the SP metro map...

Linha Azul, the blue line. The station is Portuguesa-Tietê . If you want to go to Luz, that will take you there. MASP, take it as far as Paraiso and transfer to Linha Verde and get off at Trianon- MASP.

Thanks corisco. It all makes sense to me now. I think I will get a bus to Tietê in the morning and a taxi on the way back to GRU later that afternoon just to be safe! It's so great to know there are so many helpful and welcoming Brazilians even before I arrive in the country! Have a great Copa.
