This place is luxurious, with a toaster/convection oven, cookingware/dinnerware, and TWO suites each with a bathroom, closet, and electronic safe. There was laundry and a little gym with an elliptical, treadmill, and weights. The beds were super comfy. The king bed was way wider than our king at home!!
The breakfast is pretty minimal -- bananas, bread, OJ, and coffee. Good thing that coffee shops/bakeries are a short walk away, as well as taquerias (including Taqueria Orinoco), a tasty seafood restaurant (Entremar — try the red-and-green fish), and even a Walmart down the street!
Polanco is great, albeit a little pricy. It has a lot of trees and parks, and you can walk to the world-famous Anthropology Museum and the Zoo in Chapultepec park. We never felt unsafe, there were always people walking around at all hours. The apartment building also had a friendly security guard. They were nice enough to stow our luggage in a locked room after we checked out at noon.
Note that, because Polanco is a shopping mecca, traffic in or out can be bad. It took us an hour to get to the airport by Uber, whereas, whereas it could be half an hour without traffic (like in the middle of the night). Just remember to account for that when traveling.
One downside with living here is that the walls are fairly thin — you can hear people walking, taking a shower, or moving luggage, at any time of the day. The birds also get up pretty early. Remember to bring earplugs if you're sensitive to noise.
