It's pronounced oosh-why-ya
If you go down to the beach right opposite Space entrance then turn right when you facing the sea. It's about a 5 minute walk.
It was in a different location last year. Sands is there now.
It really had that Ibiza feel last sunday....a bit of DC10 on the beach. No sign of police trying to stop it either.
It is quite elegent there though...so try to dress and act accordingly to gain entry.
