I'd give a 10/5 if possible - everything about the flat & my stay were fabulous. The unit is new & modern - perfect for 1 person, possibly 2 with a lovely spacial layout, including a desk area in front of the full length windows that run the length of the unit (which I adore), fully stocked kitchen, large bathroom, laundry & plenty of closet/storage. The bed & pillows are amazing & the linens are quality & comfy.
Juanjo is an incredible host - extremely polite, considerate and he went above what I would have expected to make sure I was comfortable in the flat during my extended stay (restocking soaps, paper products) & cleaning.
The building is safe & secure (doorman) & I always felt safe walking in the area, even at night. Especially if you enjoy walking, its easy to get around & to all the amazing coffee shops, restaurants & parks & more.
I will definitely look to stay here again when I return to CDMX!
