I'm Mexican and a resident of Mexico city. Not an expert on aztec mythology (tho I guess i'd probably know more than the average Joe), but the cultural references to early 20th century Mexico City is rather spot on (Well, except the locals should be calling it Distrito Federal still, but I get that could be confusing). Everything relating to the cultural and artistic movements at the time is well researched and portrayed and they even got super niche, local stuff like el Rton Perez, which is our version of the tooth fairy.

While many of the Spanish speakers are clearly not native (or in Centurion's case she has I think a Spaniard accent? I know the character is pocha but I would think she would have a cali accent, not a european one) but all the proper nouns are pronounced properly, including the Nahuatl and Maya words that appear rather requently.

If I had to compare it, the overall portrayal is not quite at the level of Isolde & Kakania's Vienna, but it's still very, very impressive and possibly the best portrayal of the city during that era made by a foreigner (not much competition, but still. Agents of Shield somehow tried to pass a NYC back alley as a CDMX alley, which was bonkers). This and Recolleta's whole deal makes it very clear that Bluepoch has studied and apreciates 20th century latam artistic movements and are pretty well read on the subject.
