Throughout my stay, Jimena was super helpful -- she waited for me when I was late checking in and was immediately responsive when I lost my keys and then later left my passport behind. The apartment is cozy, with basic cooking essentials and fast Wifi. The water was always hot and having a TV with Netflix was kinda nice for downtime in Mexico City!
The neighborhood is super safe, if not a bit far from the main tourist drag. Navarte does have its own share of excellent bars and restaurants, and the apartment is located about a 5 minute walk from a metro station that can take you straight to Condeza. I stayed one month, and enjoyed my time there!
