Lovely apartment in a central area great for anyone looking to visit the historical zone and shopping areas with lots of global brands nearby. It's small, so it's great for just 2 people but if you're after something more uptown where more Western-style food is, look to Roma Norte and La Condesa.
This apt has a lot of things to see and eat nearby, especially if you like historical sites like the plaza. It also has very popular street taco stands on the adjacent blocks (street food is generally safe in CDMX), just bear in mind that the apt. can get a bit of noise from so much going on around in a huge city like this and there's not a lot of soundproofing from the windows.
Overall I'd say it's a great spot for a short stay!
