First off, Paulina is a great and communicative host, even from afar. She was in Colorado while we were staying at her place and was still very responsive throughout the trip. Her mother Patricia was our contact in Mexico City and greeted us at the apartment even though it was a bite late at night. There were two small tremors/earthquakes during our time in the city (nothing serious, thankfully) and Paulina wrote immediately to check on us. We also had an issue with one of the keys breaking as we were trying to get into the front gate late at night—no fault of our hosts, I'd say it was the fault of a cheap key-maker—and when I reached out to Paulina, she responded quickly to let us know another way to get in. Since the issue wasn't too urgent once we knew the other way to enter, her mom came by a couple days later to replace the key that broke.
The apartment is really nice—for two people, it was more spacious than I expected and had character that reflects the artistic/designer interests of the hosts. The kitchen is big and has most amenities one would need. The mini courtyard off the apartment was my favorite part of the space. There were gorgeous plants everywhere, interesting books, and a TV with Netflix. The only thing that I wasn't crazy about was a spiral staircase that led to the lofted, small bedroom. The staircase (though it looked cute) was a challenge to navigate for middle-of-the-night bathroom runs and the bedroom, though clean and with a comfy bed, felt a little stuffy sometimes and was off of a roof where there were some machine-like noises at night—so if you're a light sleeper that could be an issue, though for us it was mostly fine. The bathroom was nice and the shower was fine—just be patient with the water heating up. The apartment building itself is beautiful and really well located—we could walk to so many good places to eat and could get to the centro pretty easily as well. Overall, it was a really nice place to come home to after exploring the city—it was beautiful and homey and easy to get to from most destinations.
