Looking for a spare room or otherwise sharing

Hi, I’m Fin. I’m finishing my degree this year and am looking for accommodation in and around Cardiff once I move out of student accommodation towards the middle/end of August. I’m 25 years old and have plenty of experience living in shared accommodation. I’m ideally looking to share a house, find a spare room, or any other accommodation option within my budget of ideally less than £500 per month. Please let me know if you have any suitable options!
