I stayed in this apartment for 4 weeks - one with a friend, one on my own, and had my parents visiting me for 2 weeks. It was very comfortable for everyone, there was a good amount of space, nice bathrooms, and a good kitchen. We were here for Christmas and able to cook a nice turkey dinner with my family. The housekeeper does a great job and is very nice. I work remotely, and the wifi was good for my calls & work needs.
The only note is that the living room has big window sliding doors, and the closet area is between the two bedrooms, so you have to walk from one bedroom through the living room without curtains to access the closet/drawers, unless you keep your suitcase in the bedroom. Not a big deal, just worth being aware of.
As far as the area, it's very well located in La Condesa, in good walking distance to many restaurants, cafes, and a great park. I've felt safe walking around here on my own during the day until around 9-10 pm at night. Uber is available and very affordable, so getting around is not an issue at all.
