I actually spent some great years at Unisinos and the campus in Sao Leopoldo is just beautiful, feels more like a park than a uni. The tech labs and the huge library are top tier, which helped a lot during my degree. Honestly the infrastructure there is easily the best part and it makes you want to hang out around campus even when you don’t have classes to attend.
Most professors are super qualified and really know their stuff, especially the ones with actual market experience. A few classes felt a bit theoretical or slow, but that happens anywhere, and the networking and the overall environment made up for it big time
