Andres's place is great. It is perfectly situated for those wanting to explore the Centro Historico and being close to everything. My wife and I loved the place as well because it authentic to how a lot of everyday people in Mexico city live. Sure a modern place is great, but there is something more gained by experiencing Mexico in an authentic way. I felt welcomed by the people who lived next door to the place and never felt anything but warmth.
Andres provides a space that is warm and homey, more than your typical Airbnb space in Mexico city. I would recommend it for those who are willing to put themselves out there to experience Mexico city in an authentic way.
