For those just skimming the reviews, STAY HERE.
Rodrigo's apartment is amazing, the pictures don't even do it justice. It's large, roomy, and very stylishly decorated (lots of great photography and paintings). The private rooftop was much bigger than expected and has a great view over the neighborhood. If you're interested in exploring Roma Norte or La Condessa, You couldn't ask for a better spot. My wife and I tried out so many restaurants and bars in the area, and all were in easy walking distance.
Rodrigo was also very helpful with any questions we had and always responded very quickly. He had lots of great suggestions for areas of the city to check out. We could not recommend this place more. Again, if you're coming to Mexico City, STAY HERE.
