Retired man seeking a new home. (walnut creek)

Hello, I am looking for a room to rent preferably with a bathroom, and I can afford $600 a month.
I am a longtime Bay Area resident, I enjoy cooking (and sharing), movies, concerts, reading and exercising.
I am a non smoker and non drinker.
No drama, I'm quiet, clean and respectful of other's property.
I have no pets, but am great with animals.
I need to be near public transit, and I hope to hear from someone soon! Thank you!
