This is a cozy nook in the heart of Mexico City a couple of blocks away from El Zocalo. There is always something to do around here and I could not more heavily advice you to stay at Raul's apartment if you are just traveling around and need somewhere to stay.
Also, if you are thinking about doing some work from the airbnb just know that the wifi is a little slow and can only handle one computer at a time. But, you shouldn't be working when staying in one of the most beautiful places in the world.
