On a mild, sunny afternoon, hordes of tourists stroll down Barcelona's famous tree-lined pedestrian avenue, La Rambla. They love it — the weather, the tapas, the laid-back bohemian vibe. One tourist from Australia says he's visited Barcelona 12 times in 10 years.
But the city doesn't always love them back.
In January, thousands of Barcelona residents marched down La Rambla and "occupied" the entrance to a hotel there, to protest the volume of tourists and gentrification in the city.
