We stayed here for 3 nights during our first visit to Mexico City. The location of the apartment is central to some of the best restaurants and attractions in CDMX. It's a busy area but we always felt safe walking to/from the apartment. There is also 24/7 security/a doorman who was always there to let us in/out of the building.
We appreciated the water filter in the kitchen and enjoyed the private balcony and views of the trees. The apartment does not seem to have a central heating/cooling system but we utilized the fan provided (and believe there's a space heater as well, though we didn't need it).
We were a little concerned about the lack of a carbon monoxide detector – which I don't believe is required by airbnb for some reason, but it's certainly nice for peace of mind – so we slept with the sliding door slightly open which was a bit noisy.
All in all, this was a good value and comfortable, clean, and safe place to stay.
