What regions to choose?

Hi! Reapplication with the British council is open now and I’ve worked in Andalusia and Galicia.

I’m about to apply for another year on the programme and I’m thinking about which three different regions to choose.

I want to be somewhere that’s well connected to other parts of Spain as well as in a warm climate (unlike Galicia).

I think Catalonia is on the top of my list but after that I’m torn between Comunidad Valenciana, Islas Baleares, Castilla y León and Extremadura.

What experiences have you had in these regions and is there any extra advice you could give me? I appreciate anything! Thanks
