The location: Absolutely perfect. On the map the apartment looks like it's right in the middle of the action, and while it is, it's just on the edge of a cluster of businesses. There are 4 popular restaurants within 100 feet of the front door and a pharmacy across the street. None of the restaurants are open particularly late and there aren't any clubs/bars on the block. At night it gets relatively quiet as the apartment is actually off of the street a bit. We didn't experience much street noise other than sirens and standard city noise.
The apartment: It's up on the 4th floor (by American standards) with no elevator. Not really a problem but with the altitude we did notice the walk up after a full day. There's a full bedroom with a massive king bed (maybe on the firm side for some) and a private full bathroom, plus a second full bathroom accessible from the living room. The living room has 3 couches (at least 2 were fold-outs) and a full kitchen, stocked with hardware should you want to cook. There's a massive private patio with entrances from the living room and the bedroom. Despite the listing's description, there are in fact 2 full bathrooms and it was stocked with essentials such as towels, shampoo/conditioner, toilet paper, hair dryer, etc. The only thing we had to provide ourselves was bath soap and there were no small washcloths for bathing.
Overall: This apartment was surprisingly quiet, walkable to SO MUCH stuff and one of Estefania's assistants lives across the hall and was willing to help with anything. Estefania was quick to reply to questions via AirBnB messages. While we love to stay in different areas when returning to our favorite cities, we would definitely check availability for this room again next time we hit CDMX.
