The apartment itself is great, and I wish I could leave nothing but 5 stars. Federico has made the apartment very welcoming and comfortable.
However there is a noise problem. The apartment is next door to two very loud nightclubs. From Thursday - Sunday the music played loudly from 11pm - 5am.
Federico was very understanding when I explained the problem and allowed me to check out early. I believe he's going to take measures to sound-proof the apartment. That said, if noise doesn't bother you, then this is a great apartment in a great location. If you're in CDMX just for fun and will be out weekend nights, you'll be in good shape.
For those who work while travelling, WiFi is also very strong and reliable. Shower gave plenty of hot water. Federico even bought a small space heater which was very helpful, as it's currently winter and cold at night. The kitchen was well-equipped. The decor of the apartment is very cool. And lastly, the apartment was extremely clean.
