I visited a lot of Spanish cities. Santiago, Oviedo, Gijón, León, Valladolid, Madrid, Girona, Málaga, Sevilla, Cádiz, Cordoba, Granada and Barcelona so far.

As far as the general sense of unease goes, Barcelona takes the first place. Some people there are outright creepy. I generally like the city, but I would not dare venture into the old centre's small alleys after dark.

Also, pickpockets. All touristy places have them, but Barcelona, man...

Shame, because the city is otherwise a jewel.

Yes, I agree, I lived very near to the big cinemas, next to mc Donald's, cross the street and you're in Raval. As a man, it looks a bit dodgy, but walking there in the night felt ok. I have seen some wild things there by drugged up or drunk people which have left women paralyzed from fear looking into the ground, though. I know there's more dangerous areas, with proper drug houses etc and Raval etc benefit from high police presence as it's their tourist jewel, so to say. So for women and kids it might feel more scary, almost every children park has permanent drinkers, the smell of marijuana and the occasional heroin junkie here and there. I have observed some interesting discussions between dealers and police, while the police knows most the dealers, they can't do too much, but they do have an eye on them, so it's safer than it first appears.

Btw , I fully agree that the particular rambla de Raval Is tacky, overpriced and the food is just bad. The places on the beach are much better. Ah, now thinking about it, kinda miss the city, it has many good parts and things.
