Even in the most central ones, the old quarters like the Gòtic and the Ribera, you can find squares that do not even appear on tourist maps. And in the end, that is the essence of your trip: letting yourself be led by your intuition, zigzagging through streets that turn into mazes, to finally discover Barcelona belongs to locals and visitors in equal measure, and that it always, always keeps some little corners which let us really be ourselves, wherever we are from.
You will find places that kindly invite you into a quiet retreat, like the patio at the Convent de Sant Agustí, in Ciutat Vella, and squares full of life and people, cafes, restaurants and shops, where people live their lives every day, such as Plaça de la Vila de Gràcia. Or paths and walks that take you back to the city's medieval past, like the old Rec Comtal irrigation canal, through which the water that once supplied the city flowed. Pretty little corners too, such as Plaça de Prim, in the heart of Poblenou. If you leave your compass at home and wander round the city, you will find hundreds more that will captivate you.
