The place was exactly like described and a good price for the location and just Mexico City after all. It wasn't super luxurious, just met the basic needs, but that was exactly how I expected it.
María was very responsive and helped me with all my questions and doubts. Especially considering I only booked the Airbnb a few hours before I arrived.
A big plus is how quiet the room is at night, which in my experience is very rare in such a big and busy city as Mexico City.
