Gabriela was a very welcoming host. She met me early in the morning and contacted me as soon as I arrived to Mexico City. She also made her self available in case I had any questions or concerns. As for the place, it was very nice. There's a main gate which you have to unlock in order to get in. Very safe. It's also located near the Azteca Stadium. I walked there and it took me about 20 minutes to get there. Good location.
