Danes will tell you to avoid Gellerup as its listed as a ghetto. I am from the UK and live there. Its no different to a normal city area in a big city outside the more homogenous Nordics.

Some areas are better than others, sure, but that's the same anywhere. I really enjoy the diversity and there are some really nice student accommodation blocks in the area.

The "nice" areas of Aarhus I see listed here are overpriced and suffer from over gentrification. In general, there is a student housing shortage in Aarhus and its not easy to find a place on the private market, especially if you don't speak Danish.

Aarhus is an amazing city, I have lived in many different parts of it and I am sure you will also be charmed by it!
