We enjoyed our stay at Fernando's place. Communication was A+ and Fernando even bought us a room fan during our stay, as CDMX had an unusual heat wave during our stay. The Internet was fast and reliable. The area has good access to public transit options, including metro and trolleybus, for getting to different parts of the city. Be aware that the bedrooms are facing the street and the sound insulation is minimal, so earplugs would be ideal for getting a restful night of sleep. Make sure to check out the huge Mercado Hidalgo next door for absolutely everything, from pre-made food, to fresh fruits, vegetables, spices, local mole sauce, all kinds of non-food items, etc.
