Wyndham Sao Paulo Ibirapuera Convention Plaza Hotel

The room size was good and the bed was comfortable. The only downside is that it's close to the airport, so there were some loud airplane noises in the early morning, though it was mostly quiet at night. The breakfast offered a wide variety of options, so you just need to see if it suits your taste. The price is decent for weekdays, especially since it's advertised as a four-star hotel.
