Very good location, but it is NOT quiet. I have years of experience with long term stays in CDMX, this was the worst place I've stayed, and that includes a place that had to be fumigated for cockroaches, twice!
The apartment faces into an open space with other apartments, you will be part of their conversations, fights, meetings, and the incessantly barking dog that the owner does not stop. The building is new, but of very poor quality construction: you will hear the snoring above, the vibrating alarm clock, and when they have sex. You will hear the neighbours conversing next door, and the conversations in the halls. You may experience the pleasure of saws, hammers, and drills over your early morning coffee. There seems to be little or no common courtesy for ones' neighbours in this building.
Location: very good, within 10 minutes walk of 4 metro stations/3 metro lines, 15 minutes to Metrobus, and 10 minutes to Troleybus. I am a fast walker, Bellas Artes is 20 minutes walk. Lots of places to eat in Colonia Centro, not so much in this part of Doctores, but lots of street food vendors. Outside of rush hour traffic, only about 20 minutes via Uber/taxi to the airport.
I contacted the host twice, both times she did not respond, I'm not sure why, so I had to contact Airbnb customer service; this was a first time to ask Airbnb for help. If you plan an extended stay, be sure to find out about extra towels and sheets; you may be required to launder your own because the host won't change them; I had to ask a few times.
