This is a lovely apartment in a great location, we thoroughly enjoyed our time there. The apartment is modern and spacious, and was very clean. The main view to the NW from the living room and master bedroom over the park and trees is serene and calming, but we also enjoyed warm and sunny mornings in the kitchen. So this is a great base from which to just hang out in a very special neighbourhood, La Condesa, or have easy access to the attractions in the city. Robert was very communicative before and during our stay, and Rocío, who received us, was super nice.
My only caveat is that if you want complete silence during the day this might not be the apartment for you, as the park is active and you can definitely hear some activity from below (e.g. dogs barking, some vendors, etc.). However it is very quite at night and we had absolutely no problem sleeping.
