Looking for a room to rent starting Aug 2024

Hello! I'm a 39 yr old man who will be moving to Madrid the 2nd week or the middle of August. Does anybody know any Spainards that will have a room for rent around that time? I start classes on Aug 19th. Preferred zones: Arguelles, Cuatro Caminos, Canal. Looking to rent for a year. I've been looking on Idealista, but some of their postings seem to repeat, which I found strange. Contact via Whatsapp or e-mail.
