This was my first time using AirBnB, but Gaby was very nice and never had any issues with anything. I think you can expect a few things to not work perfectly anywhere you go, but for me and my friend, it was a great, economical place to stay in the middle of a very lively neighborhood in Roma and Gaby was very accommodating and easy going. Hot shower, couple of comfortable beds and all of Mexico City around you, I really am not sure you can find a better deal on AirBnB.
