I greatly enjoyed staying at Gabriela's place. I called it "home" when we were out and about in CDMX. It is a comfortable corner studio. The decorations were lovely and the view was excellent. The security folks downstairs were incredibly helpful and friendly. The location is absolute perfection, lots of food, bars, and convenience stores nearby, and about a 25 min walk to Bosque de Chapultepec. Check out Lardo for breakfast before heading to the park! If you're a light sleeper, consider bringing earplugs, because the joyful nightlife noises can be heard even with the windows closed.
I highly recommend La michoacana across the street and around the corner for their paletas. My favorite flavor was the mango chamoy. Yum!
