Quiet retired senior citizen needs a room starting June (Beaverton OR Clackamas)

I am a senior male seeking a room started in June.
I'm cleaning quiet and respectful and I always pay my bills on time.
I have a fixed income.
I have a good references and I don't smoke.
I always clean up after myself.
I'm looking for a clean quiet room for $600 to $800 per month.
I prefer my own bathroom but if the situation is okay it's not a deal breaker.
