Rosalia's place is really nice. She herself is very responsive to any questions or needs. The apartment was comfortable and came with a lot of thoughtful touches. Rosalia gave us lots of recommendations on where to eat, etc. The neighborhood is a really good one for people unfamiliar with Mexico City: lots of places to eat, drink, get coffee, a nice bookstore, etc. Well located to the Patriotismo station on the metro. Overall highly recommended.
