Rosario's place is in a great location, walkable to much of what Coyoacan has to offer. The apartment is spacious, almost too big for two people. The bed is two twins pushed together. At night, you can hear the neighborhood dogs barking above the rooftops. Other than that, the street is pretty quiet.
The kitchen is sparsely furnished with well-loved pots and pans, minimal utensils and no paper products, so bring your own. Rosario provided a half a big jug of water to tide us over until we bought more on our own. There is a Walmart Express about 2/3 of a mile down the main road that we visited multiple times on our short stay. Also, across the street is a little bodega where we purchased beer and Gatorade from a nice man.
The shower is a little on the wimpy side, but did the job. And we had a need for more bath tissue which was happily supplied upon inquiry by our host.
All in all, Rosario's villa is a good value, well situated and furnished with the basics of what you need to have a pleasant vacation. Perhaps perfect for those who are going to use it as a home base to get out and eat, drink and explore the neighborhood on foot.
