If you're planning on visiting CDMX, this is a great location. The apartment is a 15 minute (or less) walk from two must see sites (won't share the name since that could give the location away).
Also, if you enjoy photography, this is a very safe location to store and use your gear. People regularly walk around with their cell phones and valuables out in the area. I personally felt secure, even later in the evening.
David was very helpful from the onset and was always available for questions or assistance.
If you're worried about street or road noise, I can vouch for the fact that there isn't much at this location.
I recommend a stay here if you're headed to CDMX!
