Disabled student

Hello, I will be a student at Uppsala University (Game design) and I am looking for a place to stay during my studies. I am in a wheelchair so looking for a place is a bit challenging. I would like to have a single room. Because of a wheelchair I need a place where there are no stairs into the house. In the house I can use crutches so stairs in the house are probably OK with me. However, it depends on the house and the steepness of the stairs. The maximum prize for me is 4500kr/month.
If you can offer me something I would be glad.
Thank you
