About the hosts: Leonor and Moises were wonderfully communicative - all my messages and inquiries leading up to the trip and regarding checkout were responded to within the hour. They were also accommodating of small requests ahead of my arrival.
About the building: Modern, well kept, and very well located! Nice street and walkable distance from many things, from great restaurants, bakeries, and cafés to grocery stores and pharmacies. As is common in nicer residences in Mexico City, the building has round-the-clock security at the front desk which can be reassuring for foreign travelers. Building seems to have nice amenities too, although I didn't get the chance to use them.
About the apartment: The apartment is perfectly functional for a short term stay and the self check-in and check-out definitely make things easier! There were a few small things about the finishes that could be improved (slow draining bathroom sink, a couple of iffy light switches / some missing recessed lighting in the bathroom, wobbly chairs around the dining table) along with a couple of dusty spots around the apartment but these minimally impacted my stay and the apartment felt clean otherwise. Very large bed is on the firm side and only had a top sheet and blanket so duvet aficionados like me might be slightly disappointed, although they were sufficient to keep warm / cool enough as needed. Finally, kitchen is small but functional for light food prep needs - perhaps not quite suitable for full-on cooking despite the full size fridge but definitely enough for making coffee or tea and breakfast.
That said, as someone traveling solo who spent most of her time working from the apartment, the space and its solid high-speed internet more than met my needs. All in all a good stay!
