I previously reviewed the unit in October when I did a pre-stay for our last stay which was 5 weeks long. Can't recommend this place enough for these reasons:
1) Host responsiveness - Carlos and Marisol are great communicators. Usually received a response within minutes, not that we expected that but it was certainly appreciated. They are also accommodating with any requests and issues that come up. We had a minor plumbing issue and they handled it so efficiently and professionally, can't thank them enough.
2) Location - literally steps away from everything. If you can't find what you need or are looking for, well just walk another block :) The hop on hop off bus stop is across the street and visible from the unit. Paseo de la Reforma is a 10 minute walk, Chapultepec Park about a 20 min walk, as is Condesa.
3) Views - two sides of walls of windows overlooking the Fuente de Cibeles and then the Reforma skyline. You can see both sunrise and sunset. We noticed a lot of comments of how hot the units in this building get (there are several listings there), but this unit has both a fan and AC unit in the bedroom. Mornings do get warm as the half the unit faces east, but drop the shades, open the windows, and run the fan and problem solved.
4) Space - the unit is huge and there is ample closet (walk-in) and drawer space (closet and dresser). We had 5 suitcases worth of stuff for our 5 weeks (yes, we don't pack light) and we had more than enough space for everything. Great for extended stays, especially more than one person.
5) Amenities - the unit had everything you could ask for, including fast and reliable internet (we never had any issues with it) and a full-on Smart TV. We brought our Firestick for Netflix and Amazon Prime and didn't need it. Full kitchen so we were able to make meals easily as well (but there are many tempting restaurants of all budget ranges steps away).
There are friendly doormen so security is not an issue. We were also able to use the parking space which is also guarded. The area is safe as can be, but this is common in Mexico City, and it was nice to have their presence as a personal touch of sorts.
