25 year old male looking for an accommodation in Cork, Ireland. Prospective Master's Student in UCC

Hey there. I and 3 of my friends are looking for accommodation in Cork, preferably in close vicinity to UCC campus, but could also be open to listings that are a little far off the campus area. All three of us are prospective students at University College Cork for the coming academic year, 2020-21. We have enrolled for a 1 year Mater's program, so our main focus remains study, hence would prefer sharing a 4 bedroom apartment such that everyone could get a private room for study. Our budget would range from 400-500 EUR per person/each month. Any recommendations for properties would be of great help. Thanks.
