No its definately not a myth. They don't go out to eat, specially at weekends, till 10 pm. Loads of firework displays at 11 - midnight, and then the clubs are open until 5 - 6 am. Go in a restaurant to eat at 8 pm and you will be sitting on yer own
If you live in the town you will probably find it noisy. I read somewhere that spain is the second noisyest country in europe. They like to shout, then theres the scooters and the dogs!!
After care in hospitals can be a problem as they rely on the family a lot ... families are more important here then UK
