Välkommen till Stockholm! First of all I'd like to congratulate you on having a place to live already. The housing market in Stockholm is overcrowded, the student housing market even moreso. So be very happy about that! Things'll probably be more expensive here, the dollar is weak against the krona plus we have craploads of taxes on everything. You probably won't need a car though because the public transport system is excellent. I don't know exactly where you're from, but be prepared for the winter being cold and snowy. A sturdy pair of boots and a good warm jacket is needed.
There are a lot of things to do and see in Stockholm, so it depends on what you are interested in really. Give me something to work with! I'm mostly into theatre and opera and classic art and boring stuff like that, but I'm not entirely clueless about other things.
The buxom blondes speak English very well and will probably be eager to practice on you.
By the way, what are you going to study?
