Reginas place is super! Great location with lots of restaurants and coffee shops. Safe neighborhood. Clean and tastefully decorated apartment. There was a construction right next to the building, but we were not bothered as we were out during the day. Not noisy during the evening or night.
The only negative thing was that the apartment gets quite moist and it takes a while for your towels to dry. There is however a fan that helps somewhat. Overall a great place to stay in Mexico City!
