We enjoyed our stay at Carmina's apartment in Mexico City.
It's located in an ideal part of the city in Roma Norte - 10/10 location! The views from the unit are excellent, and check-in/check-out was a breeze. The doormen we interacted with were friendly and helpful.
The only two drawbacks were encountered were that the unit was hot at night (the AC couldn't do enough to battle the heat) and that the beds/pillows were not very comfortable.
Overall, I would recommend this unit as a place to stay in Mexico City.
