It is a good location if you would like to be close to Museo Frida Kahlo. If you are unable to get tickets online go to the museo and hour before they open get in line and read a book until they do as it is a popular place.
I only saw the host Jesus Angel twice, an hour after I arrived and as I was leaving his home after three nights, and I believe it was more by coincidence.
His sister in law (who seemed to be the real host) was extremely friendly, but she speaks only Spanish. We had fun trying to communicate and she helped me as much as she could with grace and kindness.
There is more than one room being rented out, (shared bathroom). I thought breakfast was included, this is only a coffee.
If you would like to go and have a local Mexican craft beer there is a nice place that I found called Centenario 107 that is located at Av. Centenario 107, Coyoacán, Del Carmen, 04100 Ciudad de México, CDMX, Mexico. This is about a five minute walk from the home. They have a web site, http://www.centenario107.com which you can get translated by google if you want.
I really enjoyed staying in Mexico City, everyone I talked to there was kind and friendly.
