Ma. Azucena's place is right outside the center of the city. I used Uber and it worked perfect and wasn't expensive. The place was spacious and very clean. There is a kitchen with everything you need, or a $3 a plate restaurant downstairs that serves good food. The Oxxo on premises was also a huge help. It was a very safe area, I didn't have any problems. To sum this up, it is one of the best Airbnb's I've stayed in and a great jump off point for Mexico City.
