Not much to add here.
It was a lovely warm day and a friend took me for a walk in the city, visiting the Sagrada Familia, Park Güell, the Palau de Música (highly recommended), and the Hospital de San Pau. We ended up on the Barceloneta beach later in the day. It was nice and empty and we had the occasion to just chill and snack on tapas and white wine.
I’m not a very “sea person” but I would really like to spend some time on sail boat, island hopping on the Mediterranean sea.
