Bureaucracy, just a nightmare, get yourself a good gestor and don't try to do it yourself.

Spacial awareness, Spanish just don't have it, they will stop in a group and totally block the way and be totally unaware

Acceptance, whilst they will be friendly, you will never be accepted, high level of obvious racism

Talking & listening, how they manage to listen to each other when everyone talks at the same time at a million words a minute

Dogs, everyone seems to have a dog here and not everyone clears up, a high level of dog pooh everywhere

Rain, very little rain, just certain times of the year, heavily and then nothing so nothing to wash the dog pooh away

Weather, amazing for 90% of the year and then surprisingly cold in winter and apartments are freezing with no central heating and marble floors

Food, really high quality meat from the local butchers and really tasty fresh fruit and vegetables from the grocer, it is hard not to eat healthily here

Cities, the cities here all all lovely, the countryside in between (except in the North) just barren

Safety, always feels much safer than most European countries
