Looking for advices before going to Gran Canaria

Hi yall !

I'm from Martinique (French Caribbean), I'm curently in my second year of studying history at l'Université des Antilles. Earlier this year, I applied to study a semester in la Universidad de Las Palamas de Gran Canaria and turns out I've been accepted.

But that said, I would like to get some advice before going there like, are there things that I should know ? How is climate there ? How safe is It ? Should I expect weird looks from strangers ? How expensive is life there ?

Any advice/information would be welcome, thanks for helping !
