Very clean and spacious apartment in a super safe neighborhood. The airbnb looks just like the photos, and was a comfortable place to spend the week. The beds are also large and comfortable !
I thought the Polanco neighborhood was okay, there was not as much to do compared to Condesa and Roma. The food around also wasn't as good and places did not open that late during the week. There are a lot of high end restaurants around, but it felt less "local" and more touristy. But if you're looking for a quiet and comfortable place, or are visiting with a family this place is perfect.
The walls are pretty thin in the apartment though, so if you're a light sleeper it would be helpful to have earplugs. We could hear people talking and chairs moving in the upstairs unit early in the morning and sometimes at night. If you're visiting with a big group, you can also easily hear other rooms even with doors closed. Otherwise, everything else was great.
