We have stayed at a quite a few Airbnb's and this place is step above most Airbnb's for a shorter or longer term stay. We stayed here for over 4 months.
Most places in Airbnb have the basics for a short term stay, but this place feel like home. Not only is it cozy, but it has everything you need in the kitchen, bedroom or bathrooms for a comfortable stay even if you are planning to stay longer. The kitchen is fully functional, the closets are large and beds are very comfortable. Also, unlike most places in Mexico City this place has heating, which can be useful in the winter.
The neighborhood is absolutely darling, full of colonial buildings and cobbled stone streets. The neighborhood is safe and walk-able and close to all the amenities you will need. (However it is not so close to the historical downtown if this is something you are looking for).
Finally, Veronica, is an impeccable host. She was very attentive to our needs and quick to respond should anything arise.
