A great place to find cool books and magazines. Maybe one of the best in barcelona. They also have a space for exhibitions that they often fill with amazing stuff.
Sunny days I like to go to the Palau Robert Garden. Is an small garden placed in the middle of the city. The palace works today as an exhibition space, so after reading the newspaper under the sunshine, you can visit an exhibition. I love to go there to feel myself surrounded of abundant vegetation and the songs of the birds. It makes me be in a good mood.
