This narrow pedestrian street is popular for the ever-changing graffiti and other forms of urban art it bears. Don’t expect some random pictures, the graffiti usually contain messages of political nature.
The street is well-known not only for the street art but also for many good bars - one of the examples can be the tapas bar MoVida.
