Definitely a Five Star Experience. This place is great and very conveniently located. Two blocks away from "Alameda Central" and "Palacio de Bellas Artes," as well as to "Calle Madero" one of the main pedestrian streets of Mexico City's Historical Center.
Inside the place, everything was neat and nicely equipped with all the amenities listed. Wi-Fi was good for video calls I needed for work, and although I didn't use many of the extras - TV, stove, or oven - they're available (the gym's machines at the terrace are not fit for use, though).
The loft is in a pedestrian alley, so keep that in mind if you're traveling with big luggage, as you'll need to walk about a block and a half (including one turn) through the busiest part of "Barrio Chino" (Mexico's China Town) to reach it.
The place is part of a building of rooms and lofts like this one, so it has staff. As a guest, this means the help of a doorman, in essence, adding some safety to the place.
Overall, I repeat, a Five Star experience.
There was only one minor annoyance: the elevator makes a loud sound - like a long electronic ding-dong - every time someone uses it. This sound can disrupt your sleep if you can't go back to sleep quickly (fortunately, I do, yet I feel this is a meaningful detail to mention).
I've already shared this place with a few friends that regularly travel to Mexico City, and I will likely stay here again.
