I stayed here for about two and a half weeks with my partner and dog and we overall loved it! As everyone has mentioned, the location is incredible. We were so close to Cafe Nin, which has the best dulce, as well as so many other great restaurants and shops. The coffee shop downstairs was wonderful and the people who worked there were always so kind. There was also plenty of Oxxos and 7-11s nearby for whenever we needed to go grab something.
The apartment itself is a bit small but it had everything we needed. The kitchen was kind of dark though because there wasn't much lighting. And sometimes the bathroom had a strange odor at random times of the day, but maybe it was related to the sewers. Aside from that, the apartment was great! The light coming in during the morning was beautiful.
Another thing to note: the apartment is on the 4th floor. I have visited Mexico City before but I was always at ground level and this time I got altitude sickness from going up and down the stairs so much. My partner was fine, but I definitely felt a little winded each time and had shortness of breath. Just something to keep in mind in general when visiting CDMX.
Francisco did a good job at answering us quickly and making sure that we had everything we need. Definitely recommend this place, especially if you're solo traveling and it's just you.
