intensive Spanish course (Santiago de Chile)

Hi everyone, I have applied for a working holiday visa for Chile, with my main aim being to learn Spanish while there. Does anyone have any schools/courses they have done or could recommend to me?

I'm a Spanish beginner who wants to study the language intensively to start with then immerse myself in the culture. Looking at Santiago but open to any suggestions.

The courses I've found online seem quite commercial with ski lessons etc thrown in. So any help would be appreciated. Thanks for your time.
