I stayed about a month at Casa de los Paramis, and it was a wonderful experience. I arrived alone on Christmas (yup), and Cristina was very welcoming -- helped me find the place, invited me to their posada, wrote me a kind note. The house is quite big, and everyone is very friendly, so it is easy to meet people and learn where to go, eat, etc.

In regards to location, the house is really close to the blue line which in just 10-15 minutes takes you to el zocalo. The house is also super close to Coyaocan and lots of amazing street food.

The house also has a chef, Ruth, who makes juice every morning and prepares an organic lunch for the house at a very good price (sidenote: she also makes kombucha and vinegars made out of like anything you can thing of...). I ended up staying for lunch much more than I anticipated because her cooking was too hard to turn up...

So, in other words, if you want to meet cool people and eat organic Mexican food, this is your place!
