Places to search that do have listings
Blocket
https://www.blocket.se/annonser/hela_sverige/bostad?cg=3000
A general classifieds site for everything. Blocket offers a wide range of different accommodation options, from entire houses to single rooms, all over Sweden. Click on 'bostad', the 'uthyres' category if you're looking to sub-let, then enter what exactly you're looking for. Blocket is in Swedish only. This is the one which most people use and has a lot of new properties posted every day. However because so many people use it, the landlords receive a huge amount of inquiries so it can be difficult to even get an answer. You can set it up so that it sends you an email every time a new property is listed that matches your critera using the 'easy rental' function.
Qasa
https://en.qasa.se/
This website lists houses, apartments and rooms for rent. Available in English. It's free to use but note that if you find a rental through Qasa, a portion of the rent goes to the site – this is included in the figures on the site, but may mean prices are slightly higher than average. Gave the same properties as blocket just in English
Solidahem
https://www.solidahem.se/
Developer with buildings in Katrineholm - but they're also on blocket and here: https://www.solidahem.se/solidahem/lediga-lagenheter/
