I arrived as a guest, and I left feeling treated like a son. They are lovely people, caring, interesting, respectful and curious about your culture. It was very interesting to talk with them. They invited me to a family dinner, which was delicious. Regarding the facilities, there is everything you need, you can cook for yourself, the bed is super comfortable and not cold at all during the night (which is rare in Mexico city). I would definitely come back! Highly recommended!!
