Living in southern Brazil surpasses the rest of the country in terms of quality of life (especially safety) imo. As for living in Floripa, it's a pretty easy-going lifestyle, being that it's a capital that's also a subtropical island. Nightlife isn't as you'd expect compared to bigger cities, but the many beaches, beautiful landscapes and friendly people you meet here definitely make up for it. Honestly, I wouldn't live anywhere else for the time being.
