To sub-lease housing means that you will be leasing it from a private person instead of a company. For example, I may have a contract with Heimstaden and I might decide to go to Singapore and study for 6 months. Instead of cancelling my contract I can decide to lease my room privately to someone for that 6 month period, and then continue living in the room when I come back. So that is sub-leasing! The advantages with sub-leasing are that there is no waiting list and that rooms are almost always furnished. This disadvantage is that you have a restricted amount of time that you may live in that apartment/room, and if you haven’t signed a contract it is easy for the person to change the rental period/rent – not that this happens very often but it is a risk that you don’t have when renting directly from a housing provider.

The Student Union has arguably the largest sub-let housing database in Uppsala. It is called “studentboet”. That is the webpage you are visiting right now. When you find a room that you are interested in you need to contact that person yourself using the contact details you can find there. It is recommended to both email and call/SMS the person, if possible. It may help to buy an international phone card or to use a program such as Skype to ring internationally cheaply.
