Overall, we had a good stay at Antonia's place. The location is very central and easily walkable to a lot of tourist points in Mexico City. Ubers are also very cheap! The 24/7 security is great and very appreciated! If you are American, know that there is a water heater you need to turn on before using the shower (otherwise the water will be cold).
We did have some issues with communication. First, we had some issues checking in but we didn't get a response from the host until hours later (even though it was a late check in, we had notified her of the time we would be checking in). Then, we had a gas leak alarm go off (still not sure why) and we weren't able to get on the phone with her. Other than those issues, we had a good stay.
