Pretty much five stars in all areas. Communication was excellent. The place was clean, well equipped, and the location is absolutely perfect. Wi-Fi is good, service is Izzi (but not as good as Infinitum/Telmex), but good enough. I was able to plug in my computer to the modem/router in the living room.
Loved the outdoor space with fresh air. I found the location to be nice and quiet. Stayed in January and although a little cold outside, the room felt nice, I did not feel cold when sleeping.
Can't say enough about the location. Multiple Oxxo and Circle K locations nearby. Two Ecobici stations, both 1.5 blocks away. Sumesa about a five minute walk away, approxiamtely 4 blocks away. about 5-6 blocks away from El Palacio de Hierro for shopping. Tons of coffee shops with Raku Cafe just right downstairs (try the Omurice, it's delicious). Neighborhood seemed very safe and clean.
Was very happy with my stay, will definitely be booking this apartment again when back in Mexico City.
