We loved the apartment and the hospitality of Martha, the host. The location couldn't be better and we truly loved our stay in this apartment (Specially the bed, is amazing!).
Two metro lines are in a 5min walking distance, the "MetroBus" is a street away as well, this makes the public transport to be awesome from this location and allowing you to go to any place in CDMX in a very short time.
Like in other comments, the noise from the street is present, unfortunately in CDMX is inevitable. But don't worry, as far as you don't have light sleep, you will not notice the sounds. In case you have, the earplugs should do the trick.
Thanks again Martha for the excellent place! I know we'll be in Mexico again someday, I will look for you on my next trip to get this apartment again.
