So I just moved to Stockholm, and it is well known that the finding accommodation is terrible and that there is a "bostadsbrist", but I used a site called www.bostadslistan.se and I found an apartment in just a few weeks! So if you are moving to Stockholm or Sweden I highly recommend that side. I do also have some friends that used www.bostadshub.se and they were also really happy. So if you're looking for accommodation in Stockholm, I know it's hard but don't give up! Good luck
