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.
Former headquarters of the "Textil Algodonera Foundation", an emblematic building of the XIX century of neoclassical style that is a reference in the city of Barcelona. They have an excellent restaurant where you can make a good brunch and a terrace ideal for summer evenings, I usually go to design when I need tranquility and that they treat me with professionalism, ideal also for an informal meeting or a drink with a good friend.
