There are a few weird design quirks (e.g. no door on the shower, no counterspace in bathrooms), but overall spacious and comfortable apartment! Fully stocked kitchen (though the gas burners were not working when I tried), very comfortable bed, and the bathtub jacuzzi was nice (although given Mexico's drought conditions, please be ethical with your water usage!). Location is the best aspect of the apartment -- so much great street food nearby, and of course Roma/Chapultepec/Condesa all within ~15 min walk.
I liked that it was on the top floor, because that way there is no one above you making noise, but there was noise from other sources. Specifically, the neighborhood is quiet at night, but in the mornings you can hear street vendors yelling through megaphones, and oftentimes birds would also be loud (little sound insulation on walls/roof so it can wake you up if you're a light sleeper past ~8 AM).
