One star - don't book. we booked for two weeks, wanted to leave after one night, actually left after 4 nights because it was just so bad. The hosts weren't collaborative to provide a refund for the nights we didn't stay 'as that's not their policy'. We still decided to pay for a hotel for the second week just to get out of that apartment (and were much happier for it). Better to avoid that though and search for a different place from the start.
*Noise - it's a very noisy place. You'll hear all sounds in the apartment building, including every step the dog makes upstairs, and every phone call or song word by word, something that doesn't limit itself to daytime. it's basically made of cardboard. Hosts mentioned 'that's just mexico city', but we stayed in 4 other places during our stay in Mexico City and none were like that. We weren't able to sleep more than a few hours each night.
* Internet - Internet is fast, but spotty. We tried to work from there, but zoom calls regularly dropped mid sentence. In the second room calls are virtually impossible. This despite the promise beforehand the wifi is reliable. Not to mention being disturbed by all kinds of sounds throughout. It's not possible to work from distance here.
* Overall the apartment is dark (views are straight to the next building a few meters away), the floors, bathroom, kitchen (which is also not well equipped) are worn. Furniture is decent.
To end on positive note - we were offered immediate support in trying to fix the internet, which unfortunately didn't yield results. And the neighborhood is awesome.
