Luz's casita is GORGEOUS. It's outfitted with beautiful furniture and dishware and everything you might want for a short stay in Coyoacan. Luz was incredibly friendly and accommodating and quick to reply to any questions we had, before and during our stay. There is some construction going on in the shared garden right now (January 2017), but it's just for a few hours in the daytime, so you will miss it if you plan to be out and about sightseeing.
The casita is located in a nice, safe area. The cafeteria a few steps away is a great place for a cup of coffee and a mollete, and you're just a five-minute walk away from delicious tacos at El Rey del Taco. It's a pleasant 20 minute walk to the main square of Coyoacan, and to La Casa Azul, and there are always tons of Ubers around to take you to the other areas of the city.
We really enjoyed our stay in the casita. Muchisimas gracias, Luz, for your hospitality!
