Florianópolis feels like a tiny surf town with tech energy. I stayed there for a month and loved the slow mornings and loud waves. People live outdoors. Beaches, forests and a big lagoon mean you can surf, hike or paddle in the same day. The weather is mostly warm and breezy.
Most travellers enjoy the relaxed culture. Cafes double as offices. There are good co working spots and coffee shops with reliable internet. For some, the cost is a win. It is cheaper than Rio or São Paulo but some beach areas get pricey.
Things to do are plenty. I read about a weekly sunset meet at Lagoa da Conceição where people bring guitars. I ended up joining a beach volleyball game at Joaquina. The nomad community is small but friendly. Arguably not the best if you want big city museums. But if you like nature, good wifi and meeting other freelancers, this will probably be amazing.
