Alex's space was very much as advertised and looks just like it does in the pictures. It was beautiful and clean. Check in and check out was an absolute breeze. It is absolutely perfect for two people, but has the space for many more if you've got folks who want to sleep on a floor or a couch.
We were only there on weekdays, but every night was quiet in the neighborhood and the space became really nice to come back to after a long day of touring Mexico City.
We never felt unsafe in the area, and a couple small questions we had for Alex while we were staying there were quickly responded to and cleared up.
I would 100 percent stay there again and I would recommend anyone who goes to Mexico City do so as well.
