The supermarket in the lower part of the building has great variety and was above my expectations (very useful por long stays, I stayed for 3 weeks and worker every day in the apartment). The gym is very nice and it was never crowded. I did not get to use the pool, but it seemed nice and I never saw many people there.
The apartment was clean and I had no issues with noise, I hardly heard anyone in my floor, the location is convenient in Coyoacan. On the other hand, the apartment was a bit warm (to consider if you need to work there during the day), and there is little ventilation (my stay was in May so it might be worse in June-August). For long stays, there is very little equipment and kitchenware (the coffee machine doesnt work and there is very little if you need to cook), this could be improved. Overall I would go back if I needed a place to stay that is close to Coyoacan.
