My favorite part about Cuauhtemoc's place was being able to sleep with these beautiful large windows open in the bedrooms and waking up to a subtle breeze. The whole space was exactly what I was looking for, old but with lots of character, and cleanliness. There is also many plants all along the walk way to your bedroom that make the place feel even more beautiful.
As for the location, I have no complaints. It is safe in an almost fully gentrified area. If you don't want to be in a gentrified area for your whole visit you are only a few minutes walk away from the Metro which is supper easy to figure out and safe to get to. That way you can at least be staying in a safe area of the city. Before I forget, the park in front of the house is very pleasant. You can enjoy the sun and buy food or snacks from the street vendors.
