Accommodation near University of Aberdeen

I have been looking for accommodation near the university, and I am looking for an option that is nearest to the university while being very affordable.

Currently I have been considering the King Street Exchange, Ensuite Gold option, costing 125 per week (almost 500 a month)

I have been seeing posts in facebook groups that accommodations should be cheaper than that including utilities and other bills.

Do you guys think the bills are reasonable? Or should I look for other options?
