My wife, 2 year old daughter and I had a great stay at Morgana's place in Condesa. Before we arrived, her communication was excellent. Our plane was delayed by 12 hours (and we arrived very late at night), Morgana was happy to change the key pick up so we could receive it from a relative who lived a few blocks away.
The apartment itself is exactly as the photos reveal. It's basic but has everything you need. It's a great base for exploring DF. It has some cute little mexican artworks inside the apartment. The wifi was very fast. The sheets and pillows were a little worn , but still perfectly adequate. It was very family friendly (we have a 2 year old who loves exploring everything).

Across the road there are some 24 hour street taco carts that are cheap and delicious. There's also a well-stocked supermarket in front too. 10metres to the right are a few cute little cafes that are great for a morning coffee. It's a quiet spot that is 6-7 blocks walk to all the action of the area where the hip restaurants are located in Condesa.
The location of the apartment is perfect.

We would definitely return.
