Furnished room wanted (Manhattan Beach)

mature single professional (engineer) female looking to rent a furnished room with private bath and kitchen/laundry access.
I go into office 3-4 days a week (9am-6pm), and live a healthy lifestyle.
Excellent credit.
I am quiet and considerate, and need a quiet/peaceful environment to come home to, and hopefully you do as well.
Open to pet sitting for a small dog if needed.
Prefer to be close to my work in Manhattan Beach.
Flexible move in date.
