Luz's apartment is perfect to stay in CDMX, it's in a great location, close to metro and Turibus stops, and plenty of places to eat. Luz was super fast to answer all our questions/messages and attended immediately to the only issue we had, which was a light bulb that didn't work.
It's worth noting that pipes throughout the building are narrow and that means water pressure is a bit low, but that's probably true of many other places as well, so don't let it deter you from staying here.
