Can't say enough good things about Alejandra's place. It's one of our favorite Airbnbs, and we plan to stay here again when visiting Mexico City.
The location is fantastic: walking distance to parks, restaurants, mercados, and easy to go to other interesting areas in Mexico City. The apartment itself is tastefully decorated, with lots of natural light, and high-end finishes and furniture.
Only thing to keep in mind is that it's on top of a restaurant, if you're a light sleeper make sure you come prepared for a bit of noise. This is clearly disclosed when booking, so we brought earplugs and it was not an issue during our visit.
