This is an exceptionally stylish, and apparently brand new, gorgeous apartment right in the heart of Condesa, just a block or so from Parque España.
I was traveling with my father, who is elderly. We chose this AirBnB to stay in for one night prior to catching a flight back to the United States, because it is close to Chapultepec, and we wanted to be able to visit the Museo Nacional de Antropologia during our one day in CDMX. The location is superb. It is walking distance from Chapultepec, a post office, and an excellent vegan restaurant--U.To.Pi.A.
Carlos is very friendly, communicates easily in English, and responded to my questions promptly. There is also a very friendly doorman who was willing to get up at 4:30 in the morning for us to turn in our key (despite my insistence that he needn't do so and we could just slip it under the door).
The apartment seems to be very new and was maybe still being furnished, so it doesn't have a ton of amenities yet, but it has all the essentials--pots, dishes, a water filter, towels, etc. The one thing it was missing was space heaters. It was remarkably cold inside, enough that we had to wear our outdoor jackets. But Carlos, the host, found some electric heaters and bring them over a few hours after we asked for them.
