Barcelona has some of the most beautiful architecture in the world, often right next door to some of the ugliest.
The outskirts of the city seem to be mile upon mile of dull apartment blocks, and reminded me of nowhere so much as Moscow, though admittedly these ones looked a bit better kept!
But the centre of the city is a real jewel. I loved it. I spent ages burrowing my way into these little medieval streets and getting pretty lost and then I’d suddenly come around the corner and find a cathedral or an archway or a plaza which took my breath away.
