8La Rambla
It is the biggest pedestrian street in the center of Barcelona which, perhaps, is also the most known street in all Spain. Here always is what to look at, especially in the summer. It is almost completely forced by all pavilions with souvenirs, flowers and food. Walk down the street, of course, is absolutely free though, you will have a set of temptations and opportunities to spend couple of hundreds of euros, but, eventually, it is necessary to pay for pleasure.
