I stayed with Edoardo & María for two months while I attended CEPE, the Spanish language school for foreigners at UNAM. The school is within walking distance. As are a metro station and bus stops.
The room itself is very comfortable. The bathroom has two doors, one to each of the guest rooms. About half the time I was there there were two other guests in the other rooms. There was never any conflict sharing the bathroom.
The kitchen is large and well stocked with pots and pans and dishes. I was given a shelf in the fridge and one in the pantry. There are tons of restaurants within walking distance. Besides al pastor and typical Mexican food there are Chinese, pizza, excellent Japanese, hamburger and a wings restaurant.
I couldn't have asked for more gracious of kind hosts. They helped me with my Spanish and with getting to know the city. Thanks Edoardo and Maria!
