I did a stopover in Sao Paulo for a couple nights at the Transamerica Plaza. The Hotel was a decent value. The room was large comfortable and clean. The breakfast buffet was good and had a lot of choices. There were only a couple of negatives. The wifi is absolutely horrible. I would up using mobile data on my iPhone because the wifi was so slow. Also, on my first day, a couple hours after I had checked in, some new hotel guests walked into my room because reception had assigned them to my already occupied room. Fortunately I was just sitting at the desk working on my computer at the time.
