Looking for room to rent

I am a teacher who is looking for a room to rent. My budget is €500-600 per month and needs to be near one of the following metro stops : Bilbao, San Bernardo, Goya, Lista, Prosperidad. 
I am clean, friendly and respectful. I want to rent for a 3/4 month period first, which I can then extend. I can rent from 6th January 2022. If anyone has any rooms available, that would be great.
