Gonzalo's apartment is in a big apartment complex (with step-free access if that's required!), and has everything you need for a short or even a longish visit. Gonzalo very kindly met us early for check-in at last minute as we arrived in the city much quicker than we expected. The complex has a little shop for any urgent needs, and is located in the heart of the historical center. It's a perfect location to explore Mexico City for the first time.
