Hi there,
Make sure to check out if your university offers student accommodation. If they don't have specific housing or halls, they may offer accommodation services where they find you private accommodation and house you with other students.
If they can't help you, make sure to join FaceBook group where numerous other students are looking for housing or flatmates. There are also websites like Ideal Flatmate, SpareRoom, Unite Students and others where you can find available rooms and flats.
I hope I managed to help!
Best of luck,
