Overall a solid Airbnb that I'd recommend. It's in, IMO, the best neighborhood in CDMX - very safe, extremely walkable, close to tons of bars and restaurants. And easily Uber-able, usually for under $10 USD, to anywhere else in the city.
The apartment itself is on the small side - the bedroom is decent-sized, but the bathroom is tiny (there's absolutely no room next to the sink, as shown in photos), and the living room/kitchen area is relatively small. The apartment got a bit claustrophobic for working remotely all day with two people (particularly because there's no A/C and limited air circulation from the windows, so it'd get stuffy - both during the day and overnight while sleeping).
Other than size and stuffiness, though, the apartment is great - clean, well-furnished, includes everything you'd need. The rooftop deck (shared) right outside the door is a nice plus, too.
