Sounds great! I'll make a note of all these details and aim to go down there sometime. I still love Barcelona but am petrified of Estacion Sants since my Mum was mugged there. It is probably the most risky place in the whole city so please take care if you need to go through it, keep your valuables well hidden and out of site ( remember 'bum bags' etc. can be cut easily) Try not to look 'like a tourist'!!! Then once you get out  have a good time!!
