Cordoba is Argentina's second largest city. We arrived on a Sunday morning and it was dead. A ghost town. No one out. I think this is b/c Argentina's a catholic country so more stuff is closed on Sundays, and because they go out so hard on Saturday nights that people don't really get up until late afternoon on Sundays.
There's nothing "to see" in Cordoba but that doesn't mean it's not a pleasant place to pass a few days.
It feels more Argentinean than Buenos Aires — fewer English speakers, more darker skinned/indigenous people, less cosmopolitan overall.
Highlights from Cordoba: going for a run on cobble stone streets, eating dinner at a super local place where an old woman told us the menu orally in Spanish, resting in the lobby of the Sheraton after walking around for several hours aimlessly.
