We've stayed in Mexico City twice, and staying in Gabriela's place was *far* superior to the first place (in a similar location, for about the same price) we stayed.
The view from the apartment was spectacular, and Gabriela made the check-in, the stay itself, and check-out a breeze.
The location was ideal (great neighborhood -- safe, walkable, and close to many bars and restaurants), although it was a tad noisy at night (but I'm a heavy sleeper). But it's the largest city in North America... of course there will be some noise on the weekends. But being 10 floors up, it was muffled quite a bit.
The decor was quaint, the space was clean & bright, the wifi was quick, the water was hot (once you figured out the shower), and overall, Gabriela's place was perfect for our stay.
We would definitely stay here again next time we're in CDMX... and so should you!
