We really loved staying at Gabriela's place during our trip to Mexico City! The location was great and so close to restaurants, bars, and beautiful tree-lined streets. Gabriela was also professional and super responsive to any messages or questions I sent during our stay, so I never had to worry about anything apartment related. The view from the apartment was also spectacular and a highlight for me.
One tip for future travelers: this might not be the place for you if you're a light sleeper. The apartment is above a row of restaurants that either play music or have musicians who play outside / on the corner. I never had a problem with this and slept soundly, but my boyfriend is a light sleeper and said the music sometimes lasted all through the night.
