Quit looking and book this bnb. It's in a great neighborhood with lot's of cool cafes and resaurants. The hosts were welcoming and friendly, the room spacious and clean, and the building secure. You can catch the near by metro to anywhere in the city, and you're a 20 minute walk from the Bosque de Chapultepec. Oh, and the wifi works really well. I'd definitely book this again if/when I return to CDMX.
