I was in CDMX by myself for eight days, the full duration of which I stayed at Gnilane's apartment. As her description provides, her place is a small room with a futon bed, desk, and bathroom (keep in mind this means no kitchen, though there are means to make coffee or tea). I would say this apartment is perfect for the solo traveller, as it provides the basic necessities, and Roma Norte is an awesome neighborhood, walking-distance from plenty of cool bars, restaurants, and surrounding neighborhoods (like Juárez and La Condesa, which are also cool areas). I felt safe walking around at night. Wifi signal was weak (which, as far as I could tell, is common throughout CDMX, including cafes where I worked while there), and the futon was a little uncomfortable, though I adjusted after a couple days (so, if you're looking for something fancier, this might not be the place for you, but great for a lone traveler on a budget!). Gnilane was very communicative, and the family that lives in the apartment across the hall was kind and accommodating. Thanks for everything!
