Our family of 5 stayed at Katie's place during a month in Mexico City. It was fantastic! Unlike so many Airbnbs now, this is actually their home, not just a short-term rental. As such, it was fully furnished and stocked which was so nice for our family.
The home is very stylish and quite large (3 bedrooms + and office). The location is right on the outside of Condesa so opening the windows (and there are a ton of them!) can get a bit noisy, but it was very close to Chapultepec which was definitely worth it! Also, Katie was very responsive, helping us with some small things that broke during our stay. Overall, highly recommended.
