Doña Minerva and don Héctor (and their son, Héctor hijo) are wonderful hosts. The room was kept immaculately. The bed was sturdy enough for me (I am tall and very heavy), and when I feared the chair wouldn't be, they provided me with a great big throne. Héctor hijo picked me up at the airport, and dropped me off there at the end of my stay --he's working part-time for Uber, too. There's a small breakfast space, which I didn't use, and they regularly rent multiple rooms, so really it was like a boutique hotel, not a "couch-surfing/AirBnB" place. It really is catty-corner from the Frida Kahlo Casa Azul, and all of the other gorgeous sights of Coyoacán are in the easiest walking distance. I couldn't recommend it more highly. Terrific!
