What is it like living in Sweden?(Hur är det att bo i Sverige?)?

My grandfather was from Stockholm, so I have a very Swedish heritage.
I'm from the United States and someday want to move to a different country and I really want to move to Sweden.
How different are they?
And is learning the language difficult?
Thanks for any answers.
Update: I also speak a little bit of the language. I have dark blonde hair and blue eyes?
Would I fit in decently?
Not saying that I want to, anyway.
