my impression is that its a city where the main attraction was the vibes and now the vibes are gone. the tourist land bit of barcelona is notably uninspiring i think. the gothic quarter and all of that. the ramblas feels like it might have been something once, but it's been converted to something else now that it's mostly for tourists. i really enjoyed the first time i was there though, i was like 21 and hadn't been hardly anywhere in southern europe, and at that point it really ticked those romantic boxes. if it was me i'd get on a train and go somewhere else in spain or france. or find whatever bits of the city are outside of the tourist bits. you could probably get up into the pyranees easily enough, that's the best bit of spain i've been to, all these little deserted bleak stone towns
