Staying with Abraham, Paki and their little one was exactly what I was looking for - somewhere relaxed and comfortable. The area, Colonia Guerrero, is a real Mexican neighborhood, full of street life and always busy - I never felt unsafe. It is within walking distance of the main plazas and central part of the city and just steps away from the metro and metrobus lines. The house itself was clean and spacious and Abraham and Paki were wonderful hosts - easy to chat with, shared lots of great info about the city and yet gave me lots of space to do my own thing. I stayed in a quiet room upstairs, where I slept soundly! Abraham also lent me his metro pass and there were bicycles available -- a nice surprise! This is a great place to stay get to know the somewhat grittier side of the DF and not just the upper-scale areas... highly recommended.
