Use Both Apple Maps and Google Maps
Buenos Aires is a rare city where Apple Maps actually pulls its weight.
In a lot of places, Google Maps is the only reliable option. Buenos Aires is different. Apple Maps worked well, and we used both apps constantly.
The real reason to run both: business hours and details weren't always the same. Sometimes Apple had updated info that Google didn't, and sometimes it was the opposite.
**Do this:** Check both before you commit to a long walk or show up hungry to a "closed" restaurant.
