My stay at Carlos's was perfect. The place is large and has large table for work. I was there a whole month so go to know all the little things that needed "some" attention and Carlos was right on it. (Needed kettle, few more hangers & door latch confusion on my part.) The place has a lot of light, is quiet, has hot water and comfy bedding. The kitchen is a bit small but most probably would go out, it has eveything one needs though, even micro and blender! Wifi fast no issues, lots of mirrors and small lights around too. The area is safe with the Metro 1/2 block away to go all over the city. There is a large grocery nearby called Chedraui but also a health food shop and many little food stores about plus basic OXXO type. One can walk to center of town 10 min and it is a lovely walk. As a single female 1st time in Mexico City, it was perfect and I would stay again. It was very cold, the building colder than the apartment, but I bought a small space heater since I was going to be there for the month and left it with Carlos so maybe you might want to ask for it if you go in the winter. Carlos was fine with me using it but I did offer to pay a bit extra if elec bill high. I highly recommend!
