Spanish Language Course (Mexico City)

Dear Friends,

My little 19 year old sister is coming to Mexico for a month. Among others she is planning a Protected content intensive Spanish course. Does anybody of you have a recommendation?

As she is travelling alone, and I am not able to take off too many days, it would be great if the school maybe even offers some extracurricula activities. I think it would be nice if there are mainly students of her age.

Thanks for your advice.
