There are a lot of norwegians especially around Alicante. Seeing also a lot of french car signs at the summer aswell.
The universities in Norway are known to be pretty good. You should absolutely do some research on google, it might be a amazing experience for you. Maybe you also get the opportunity to find a part-time job next to studies :)
Oslo, Bergen, Stavanger and Trondheim are all great I guess. But since im from Oslo, thats the best place to go + its the capital.
Btw I love Spain, me and my parents have a house in Alicante. Spanish girls>all!
