Native Swede here. Welcome to Sweden! I take every opportunity to make a point of welcoming Russians to live and work here, while at the same time denouncing Russia's regime. Being afraid of the Russian Federation and her recent actions is not the same as being afraid of or disliking Russians. Just wanted to get that out...
It's really rainy and cold 8 months a year, if you live in Stockholm or south of it. If you live up north, it's at least cold and snowy and beautiful4 of those 8 months, instead of rainy. I love the summer in Sweden, but it's so short. The Stockholm winter climate just sucks, sorry. It has to be either colder or warmer for me to like. Mud and rain is not my thing.
