I lived at Evelyn's place for 5 months and I like this place a lot.
Good things about the place: The location is 5-10 minutes from Reforma, and has good restaurants and coffee shops nearby. The place has all amenities needed for a long stay, including full kitchen, all things you need for bathroom, laundry, cleaning service, walk-in closet, and additional sheets and blankets. There's security at the building 24/7, and they are very helpful. Evelyn is very nice, she helped change a new heater immediately when the old stopped working, also she brought a green plant for Christmas which was sweet :)
Things to consider: The apartment is very close to main roads, so it can be noisy sometimes. Normally it's fine but weeks before Christmas, you can hear people partying nearby especially at Fri and Sat nights. There's no elevator and there's stairs inside the apartment, but it was ok, nothing inconvenient (unless you get injured with legs). Another thing is I lost 2 personal belongings during my stay, I know it's not the host's fault, it can happen anywhere, but just remember to keep things safe :)
Overall, i will recommend this place :)
I had to move out only because someone booked the place, it would be nice if I could be advised to extend my booking in advance T^T
