We're a family of 4, visiting Mexico City for 5 days. After exploring the city, I would definitely recommend anyone to stay in the Condesa area. On top of this, Ana's place is perfectly located. Regarding meals, you can find gourmet-style taquerias, coffee shops, or casual healthy/organic restaurants at a walking distance. A big park for running and working out is also at 3 minutes walking. The Chapultepec park with its zoo and the beautiful Anthropology museum is also a short walk away.
Regarding the apartment itself, we found it perfectly clean, exactly as described in the pictures. We landed in Mexico a bit late but Ana's friend was waiting for us at the entrance to give us the keys, shows us around, share some recommendations and make sure we were comfortable. The street where the apartment is located is completely safe, even at night, but gorgeous in the morning with all the plants and trees surrounding the walking path in the center.
I would definitely recommend Ana's place for anyone looking for a place from where to explore this great city.
