So first of all, I really was not impressed. Are there any special areas that could make the experience better there? I visited the Park Güell, la Rambla, was staying in a flat right across the park of Sagrada Famiglia, the gothic quarters and all that, but wasn't much impressed. The gothic quarters I liked and a Flamenco Show was absolutely spectacular, but the others imo were just meh.

What is the obsession with dust? A lot of areas were with walking paths/roads which were dusty.

I liked the public transport. The metro and the buses were very useful.

What I wondered, and I hope I don't offend anyone here, why would the Catalans want independence from Spain? From what I saw they have a high level of autonomy. Everywhere the first language was Catalan and the Spanish. Is there something I am missing here.
