Fabiola's place is great! I stayed there for 8-9 days. And I was out most of the time as it was my first time to CDMX and I wanted to explore the city. But it's a very central location, in a beautiful neighborhood that's walking distance to a lot of great restaurants / parks / museums / monuments, etc.
Her place is a great deal in that respect, and at a great cost. Fabiola extremely warm and welcoming host, very easy to communicate with. Overall - I would highly recommend staying there.
