Here is a good place near Canastra Sierra, a very famous place, where you can have contact with nature, and experience adventures. The city is small, it has 100 habitants, but you can have lots of places to visit, like night life interactions, cinema, bars, etc.
Our students are very polite and curious to know more the language. We use National Geographic materials, but we focus on Speaking classes. We are an authorized CEFR Exam Center, and every year our students can evaluate their knowledge.
