My husband and I stayed at Eloy's apartment with my brother for a week long visit to Mexico City and it fit our needs super well! The apartment was clean and is in a great location - really easy to walk to the park and even to Roma, Condesa, etc. (also a very short Uber ride if preferred!). The area is safe and the building felt very secure due to the constant presence of doormen. We would recommend his place if you are looking to stay in Polanco - and the AC is definitely a plus!
