BARCELONA SPAIN TOURISM - AP 10-14-19 5.jpeg

This Oct. 7, 2019 photo shows the interior of Barcelona Cathedral in the Gothic Quarter of Barcelona, Spain.

The city is dynamic, the streets and cafes are always packed, it’s safe to walk around at night and people mostly speak English. (Courtney Bonnell via AP)
