The apartment is a great location in Polanco. It is right next to many breakfast, lunch, and dinner options within walking distance. The building is also extremely safe with 24 hour security from very nice/helpful security guards. The apartment is also HUGE with tons of open space and a great view. Derek also provided us with plenty of free water bottles which was super helpful.
However we felt that the overall quality of the airbnb was mediocre. You can tell in little things like the quality of the carpet and the showers. In terms of specifics, the stove and microwave didn't work that well, and there was a poor supply of pots and pans. All the twin beds were uncomfortable, and you could feel the springs through the mattress. And while it is listed in the details (although we didn't notice at the time), but the lack of wifi and heating was frustrating (Derek provided us with extra blankets and a space heater for one of the three rooms).
