Maria's place is a great deal for the price and location. Being only 5 minutes away from my office made it perfect. Great location for traveler's. There's an Oxxo right across the street from the apartment, and lots of restaurants, etc nearby. Coyoacan is also only a couple miles away. Will stay here again when visiting for work!
Note: If you're like me and this was the first time you are in CDMX, everywhere is fairly high security, and most apartments/buildings seem to have security. So, if your Spanish is limited, be sure to work out ahead with Maria and the security at the door.
