These are two of the streets in La Ribera, a medieval labyrinth of alleys where it's almost impossible not to get lost (and let's just say I speak from experience.) I loved that almost every balcony had laundry hanging from it. In Paris, where there are balconies on almost every building it's illegal to hang laundry from them, but they're apparently more practical in Barcelona. Every street seemed to be celebrating some exuberant holiday with dozens of multi-colored flags waving in the breeze.
Even if you live in Eixample, in a spacious building with a view of Gaudi's La Pedrera, apparently you never want to let a good balcony go to waste.
