We started off by being dropped off at the wrong corner in the dark in a city we're unfamiliar so it took a minute to find the front door of this building (which is non-descript whatsoever). When I emailed asking for the building name or better directions I was informed that the directions provided were "good enough" and we eventually did find it.
The check-in process was quick and smooth. There is a 24-hour front desk person who confirms your identity and provides you with a key to your apartment as well as an elevator key card. Don't lose either of these. We were on the top floor but the buildings are all about the same height so there isn't much of a view (the listing didn't list a view so no worries there). The apartment itself is quite small so it's good for a short stay but definitely wouldn't be functional for extended stays.
Kitchen: equipped with 1 fork, spoon, knife, bowl, plate, mug and 2 drinking glasses per person. There is a 2 burner hot plate, mini-fridge, microwave provided. Most drawers are empty but there is a cutting board and a knife set should you feel the need to chop/cook. The trash can is insanely small so keep a plastic or paper bag to hold any bottles or other trash you need to take out each day. There is also a Brita pitcher, which is great in theory, but it was disgusting from prior use and who knows when the last time the filter was changed. We bought bottled water.
Living room: there is a comfy transforming type loveseat with a coffee table and a decent sized TV should you feel the need to watch. The WiFi setup is just below the TV and easy to access info from. There are floor to ceiling windows with privacy and blackout shades (although with the sun coming directly in the majority of the day, they're not really "black out"). One window opens in the living room, and you'll need it because there is no other climate control in the apartment. We had to move a plant out of the way to open it but no biggie.
Bedroom: The closet is enough to house everything for your short stay. There is a luggage rack to keep your suitcase off the floor and/or the bed. Hangers, a small safe, a fan, an ironing board and an iron that looks like someone ironed their gum with it. There is a big hole in the ironing board so it appears someone melted the iron into the board and this has yet to be rectified. You can't use the iron. It's cheap and weak and damaged. Bring your own iron if you think you may need one. The bed is ROCK hard and you only get 1 basic pillow per person. We were so incredibly uncomfortable on that bed that my back still hurts 3 days later. There is another window in the bedroom, but we definitely had to pull the fan out to move air around during the day and help drown out some of the noise at night. This place is NOISY. If you need quiet to sleep and you stay here, bring your earplugs!! There are lamps at either side of the bed, but the lamp on my side didn't work. I'm assuming the bulb was out but there are no replacement bulbs in the apartment so we just didn't use it.
Bathroom: this was quite possibly the nicest part of the apartment. The shower and toilet are both private and separated by the sink with large counter space and mirror with decent enough lighting to do your makeup. If you're not comfortable doing #2 in front of your travel companion, this could be a little tricky... there is privacy glass, but nowhere for the other person to go and not hear what's happening. The bathroom mirror is the only mirror in the whole apartment so hopefully you are tall enough that you can see your outfit before going out. The toilet flushed mostly well and the shower had decent water pressure. They do provide shampoo and body/hand soap. 2 rolls of toilet paper are provided and if you go over that you will need to supply your own. There was no Kleenex and my allergies were out of control so we did need to buy a few things to resupply. There are only 2 bath towels provided and 1 hand towel for drying hands after washing, as well as a floor mat. I usually use 2 bath towels myself so we had to improvise. Not having enough smaller towels to wipe our face with was a bit frustrating. If that's a concern for you, bring your own or expect to buy some.
Location: amazing if you want to be near the Zocalo and shopping. Its all just a few short blocks away. Super walkable area, close to the Metro and easy to catch an Uber or the bus. It is LOUD. Like extremely noisy in an already noisy country. Horns are constantly blasting, the sounds of trash being loaded, people shouting. Mind you, it's a busy downtown area and it's great to be close to everything, but if you need peace and quiet to sleep this may not be the place for you. Definitely bring ear plugs or something to help drown out the noise at night.
Shared rooftop area: We were able to watch the fireworks from the rooftop area which was nicely stocked with tables and chairs. We even had take-out dinner up here one night. The "gym" is nothing to write home about - literally just an elliptical and a treadmill.
Overall the stay was fine. This was our 3rd AirBnB stay in CDMX and the first time in this particular area. I would not stay in the area again because I find other areas more appealing and Historic Centro is just way too busy for my liking.
