I can't recommend this AirBnB enough! I visited Mexico City just after the earthquake and let me assure you, Roma Norte was thriving still. Mariana was the ultimate host, always available and filled with stellar recommendations for the neighborhood and city as whole.
I traveled solo to the city from New York and the apartment couldn't have been in a more perfect location. Lively, hip, deeelicious food. It's across the street from an adorable park where I watch people play with their dogs. I walked to dinner every night by myself and felt perfectly safe! There a number of great coffee shops, restaurants and shopping within a stone's throw of the apartment.
The apartment itself was impeccably clean and very comfortable! I had plenty of space to unpack everything and feel right at home.
I'd highly recommend Mariana's AirBnB and Roma Norte!
