we stayed one month. location of this place is perfect: neighborhood is very nice and safe, you can walk east and get to Paseo or walk west and be in Polanco in few minutes. the place, on the ground floor, is very private because it is inside the main property, so you are not out in the street. it is also very quiet, both during day and night, since the main street is mostly residential. the place offers a separate table that one can use as work desk, so it works well for digital nomads, since internet was good.
the best thing of this place, however, was the host, Federico: both professional and friendly, he answered all our questions any time of day and night. he gave us timely and clear instructions for check-in, with a plan A and a plan B in case plan A (using an app to open a lock) would not work (like my phone run out of battery ...). really good at planning things so our stay would go smoothly, it was a great pleasure to work with him and we highly recommend him.
