I will also be in Stockholm. I may have found an apartment, but I need to register as a student in Stockholm before I can get it, and my hosting institution is Lund, even though my fieldwork is based in Stockholm. So I'm trying to figure this all out, and quickly. Good luck with your apt search, if this one falls through I'll be right back in there with you.
Is it just you, or with you be with a partner or family? I will be there with my fiance.
