I know exactly what you're saying. I love Catalunya. The people there put other people at the top of their priorities rather than money.
Sounds like a fantastic trip. Did you do much sightseeing amongst all the partying?
Before we went, we worried that two days wouldn't be enough, but I don't think our bodies could have taken any more.
We didn't do any real sight-seeing as such, but just wandering around we saw a lot, the Gothic quarter, the waterfront, several Gaudi buildings - didn't get to see La Sagrada Familia which is a pity. Having said that, I generally don't do the 'tourist' thing, prefer to go off the beaten track, find a nice cafe/bar/club, hopefully meet some locals, have a chat, make some friends.
One (of many) funny experience, as I went to the gents' in a nightclub there, the guy ahead of me turned and made some comment to me about the club, but in English with a Spanish accent. I asked (in my best Spanish) "hey, why are you talking to me in English? I could be Spanish!" - he replied "No, you couldn't possibly be Spanish". "Hey! Why not???" At that instant another guy came out of one of the cubicles and said "Sorry, no way could you be Spanish!" and walked off.
Great people, and a great city. When were you there? Definitely going back, hiring out an apartment and staying longer this time. It was a far better bonus that cash, to be honest!
