This is such an important point to highlight, especially for first-time visitors who might assume English is widely spoken in a capital city.
I found the same thing on my trip, and relying on a translation app was a lifesaver for everyday interactions like ordering food, in a shop, supermarket, or even asking for directions.
It also made me realize how much locals appreciate even a few attempts at speaking Spanish, which adds to the overall experience.
Thanks for sharing!
