I lived here for a month and it is a super sweet little hobbit hole of a place that works really well for one person. Sergio & his wife are the absolute sweetest and literally responded to every request within like 20 minutes & I made some pretty fringe requests at times (like when I needed craft glue and they came thru with the biggest container of artsy glue I’ve ever seen in my life). The hot water always worked & the wifi was dependable. I want to echo that when there’s folks in the upstairs apartment you can hear everything including like the TV but also them walking & talking & doing, um, other…things. But when no one’s staying above it’s a pretty quiet retreat of a space except of course for the ambient street sounds which I don’t think you’re ever gonna escape in Mexico City anyways.
