Does anyone have experience with the "Spanish Immersion School" (http://www.spanishschoolinmexico.com) in Oaxaca? It sounds great (one-on-one instruction with university-trained professors, lessons tailored to cultural activities, etc), but I can't find any reference or reviews anywhere, which worries me.
I am planning to study for a week next month with my 9-year-old son, and am hoping for a place that will be appropriate for both of us. (We are both intermediate-level speakers.) We are also interested in a homestay, and I've heard not-so-good things about ICO's homestay setup.
