I stayed at Diana's place for a little over a month. I would definitely recommend for the value, location and the host.
Roma Norte has a lot of great food options. I preferred to eat local mexican food, but I also used Uber Eats for other types of food.
There are really great parks and museums all within walking distance. The neighborhood is safe and I had no worries walking around by myself.
Diana is awesome! She is very welcoming and a fun person to hang out with. If you do stay, don't be afraid of asking questions or starting conversation!
