I had a wonderful time staying at Casa Lucero and highly recommend it to anybody who's looking for a beautiful, clean, tastefully-decorated apartment. Initially I was a bit worried about two main windows which face the street -- I'm a ridiculously light sleeper -- but, sans the occasional neighbor buzzing in, the entire place is very quiet. I stayed a whole week and was never woken up or bothered by any noise. At night the place is dead silent.
The pictures in the Airbnb listing are very faithful to the real deal, but there are many little perks, such as a great collection of books and guides, which should be very helpful to any visitor. The kitchen has anything you could possibly need -- including spices -- in case you feel like cooking (the fridge is stocked with few snacks, which can be purchased cheaply). But, honestly, there's so many great restaurants in the neighborhood that I really doubt you'll want to fire up the stove for any reason.
As per the location, if you don't know Mexico City or if it's your first time visiting, Casa Lucero is located next to some of the newest and trendiest cafes & restaurants (and plenty of old-school classics, too). Everything -- a 24 hr taqueria & juice bar, bakery, an American-esque supermarket, a gourmet European market, corporate & hipster cafes, street vendors, an OXXO (a Mexican 7 Eleven of sorts) -- is within a one to four block radius. You'll also find a huge, beautiful park just one block away. Honestly, even though I live in Manhattan, where there's a bodega in every other corner, I left feeling very jealous of Casa Lucero's access to literally everything.
I do have one minor critique: WIFI can be very inconsistent. Even after rebooting the router, at times the internet was practically unusable. Other times it seemed to work perfectly fine (I was able to upload a large file quickly and stream a few movies). This is probably more of an issue with the internet service provider than with Casa Lucero's equipment, so it's not fair to blame the host for the spotty service, but just so you know.
I'm a frequent CDMX visitor and have stayed in various places in different neighborhoods. So far, Casa Lucero is one of my favorite spots and wouldn't hesitate to stay there once more.
Again, I highly recommend it.
