Good for you. I usually stay at Intercontinental when visiting SP. They don't have central heating. They can provide you with a space heater in the room upon request, but a space heater does not deliver the adequate warmth like the central heating that we in N. American or Europe enjoy. I am not aware of any hotels with built-in central heating in SP, but I would love to know if there is any. None of the bars, clubs, restaurants, sauna have heating. So, I should have stated, IN GENERAL, there is no heating in Brazil.
