Hotels at the Mexico City Airport

I most definitely dislike the thought of being there for a few hours, simply because it wouldn't be enough!!
I need more like a few weeks or months.

I'm from the U.S., wife is from Mexico.....and we met in Ixtapa in the 90's while we both were vacationing.
Come to find out she was from San Angel, beautiful town in Mexico City.

Although I love my beach vacations, I have absolutely no problem spending a month visiting and bouncing around all the different areas and smaller towns around the DF. So much to see and do.
