@ossobuco,
The true reason behind the thread is that I feel that Mexico City is often overlooked, amid prejudices about the country.
It is, indeed, a great city.
So far, we have only seen an important part, not all, of Centro Histórico. Only a small fraction -small, I insist- of what the city has to offer.
Travellers with an acute eye -my German daughter-in-law, our Robert Gentel- have noticed that this is not just "a city", but several intertwined cities-boroughs-neighborhoods, each one with a different history, with different flavors, different architectural looks, different rythms and different kinds of people.
