Stockholm at 59.33°N is about .5 degree North of Churchill in Northern Manitoba. Without the Gulf Stream your friend may be in for a rude surprise: polar bears rather than grapes and olives.

> Churchill is a town in northern Manitoba, Canada, [...] most famous for the many polar bears that move toward the shore from inland in the autumn, leading to the nickname "Polar Bear Capital of the World" that has helped its growing tourism industry.

Thanks to climate change, by 2050 it will be blessed by 14 summer days, up from 8 in 2021. Not sure that's enough to scare the bears away.
