Location, location, location! Fabiola's place is located in the safe neighborhood of Roma Norte (walking distance to the hip La Condensa/Reforma/Zona Rosa neighborhood, several parks, the Chapultepec Castle and et cetera). Lots of shops nearby, uber is cheap (but do give yourself enough time as traffic in Mexico City can get pretty bad). Despite how family and friends were worried for me back at home, I never felt threatened being by myself.
Make sure to arrange check-in with Fabiola as she does work full-time till 6pm. There was some hiccup, but wasn't of concern since I was tired from my flight anyways. You get what you paid for, it's great for someone like me who travels on budget. Lots of privacy in my little rooftop den, however you will hear city-noise throughout the day/night; didn't bother me much though. There are 3 other rooms rented out to other airbnb tenants, I saw them at passing and talked to a few. There's only 1.5 bathrooms but everyone was respectful of each other and we never bumped into issues. Fabiola also has a big filter in her kitchen so you will always have clean drinking water. Outside of that Fabiola, even though I didn't see her much throughout the day, she comes back to the property to check on me daily, which I thought was nice.
Thank you for letting me stay at your place!
