We really enjoyed our stay at Pilar's home. Pilar was not there so we were sharing the house with her cousin Martha. The place was very cute, nicely decorated and very big with several outdoor spaces. The home itself was in a lovely community and was gated so we felt very safe. Martha was easily the best part of our stay. She was warm and welcoming, made us food, was very thoughtful in picking us up food for our bus ride, and was very easy to talk to. We loved staying with her, she made us feel like family. We were able to stay in the upstairs room which was nicer to be in as a couple because there was a bathroom in the room instead of having to go outside and down the stairs to use the bathroom at night.
The only minor negatives were the distance (about 10/15 min to central coyoacan), there was no fan provided (this was tough because we had to leave the upstairs balcony doors open and I got eaten alive by mosquitos at night) and the meditation room was locked unfortunately because Pilar was not there.
We would absolutely stay here again if Martha was there, she was one of the best parts of our month in Mexico and we'll always think back on our stay fondly.
