My praise is so high that it can be stated simply: this is one of the greatest places I've stayed, anywhere.
The apartment is lovely, cozy and well-equipped. But the secret ingredient is the family that owns the main house. They are exceptionally knowledgeable, curious and kind. (That includes Mateo, the family dog.)
And the neighborhood: peaceful, lovely and nice for a walk -------------- really an escape from the craziness of 2020-1.
5-stars.
Oh, I should mention that the family has some other properties too, of different sizes, types and prices --- even in Oaxaca. I haven't looked at the details myself, but I would look at their "host" page for more info.
