I'd love to find a homestay near or on Lake Atitlan, for a low budget traveller which is centered around a course, be it crafts or cookery if possible.
Hi Ellen- I would highly recommend a cooking class on Lake Atitlan with a local indigenous lady who speaks great english, Anita. Here is her website! http://www.lakeatitlantravelguide.com/product/lake-atitlan-guatemala-cooking-class/
She charges $35 and you go to the market with her to shop for ingredients and then you cook together at her beautiful outdoor kitchen on the lake! It was wonderful ;)
Contact Celas Maya Atitlán. I did their Spanish/homestay program in Xela, and they recently opened a new location in Lake Atitlan. Quality instructors and they keep on top of the homestays to make sure you're comfortable.
