I did my undergrad at Konstfack in Stockholm, Sweden.
Really enjoyed it there with a strong design and art legacy both within the school and the city/country.
Other more famous options in Sweden are Lund in the south and Umeå in the north.
If you like California, I’d maybe discourage committing to the north of Sweden though 
Sweden is a great country to study.
While living costs are relatively high, you do get to enjoy a safe and diverse country with great healthcare and a dependable infrastructure.
I am Swedish/EU citizen, so I studied for free but I believe that even for international students, tuition is no where near US standards.
The masters are pretty competitive though as classes are small and application numbers are high.
Shoot me a PM if you got any questions. Happy to share more about my experience.
