This is a legit listing, the best place I stayed in Mexico City! The location is good, the building is safe, and the apartment is beautiful. The hosts are pros - very responsive, and all the furnishings are good quality. If I were to nitpick, it would be you can hear the neighbor if he/she talks loudly on the phone, etc...but I was able to drown it out by turning on a fan.
All in all great hosts, great place, great experience.
