5th stay in CDMX and this is the best Airbnb I had. Stayed 2 months.
Perfect location, excellent communication from Karla, reliable Wi-Fi, comfy beds, quiet (which is hard to find in CDMX), great natural light, well stocked, consistent warm water in the shower (a rarity in CDMX), secure building, clean building, suitable window shades (updated from past reviews). You will need to wake security if you come home too late (they are so super nice about it tho).
I hate to write anything negative ( Karla has no control over this), but it may be important to some people... The residence in the unit below smoke weed on their patio daily. Not an issue with the patio door closed.
Even with this minor downside, I would stay here a thousand times over. One of the best Airbnbs I've ever stayed in, and such a great option in Mexico City. Don't hesitate!
