I had some crazy travel interruptions during my trip and ended up stuck back in Mexico City for an extra night without anywhere to stay. Flavia and Mauricio were extremely gracious in responding to my message on Airbnb from my previous reservation from about a week prior and got me set up with a place to sleep for the night. That was really nice of them and helped me out a lot!
As for the apartment (I've stayed in two of theirs now), I've got to say that they are easy to find, secure concierge, wonderfully designed with nice decorations (my girlfriend would have loved it), and the rooftop was amazing. The location is perfect for exploring the Historic Center, and the fresh Mexican coffee in the fridge with a few bottles of fresh water is definitely a nice touch.
I will be reaching out again if I find myself back in Mexico City! Thank you so much!
