Quiet, retired single woman seeking rental

My name is Nancy, I am a 65 year old retired woman looking for a long term rental as my previous rental was sold. I am temporarily living with family but would love to have my own space again. I am very quiet, do not smoke and have no pets. I do not drive so somewhere central or near a bus route would be preferred. My budget is approximately $800 a month. Please call or email my son as I do not have email and my cellphone reception is unreliable!
