The Casita is an addition to the main house with a private entrance to the side, fully furnished and independent from the main house with kitchen, washer/dryer, king bed, TV, etc., and high-speed wifi, heater and AC. There is a door slider beween the main house and Casita that you can lock.
You will have access to the back yard with pool, jacuzzi, fire pit, or just chilling out and enjoying the awesome view of Saddleback Valley below. I can also provide you access to Lake Mission Viejo as my guest, swim, sail, house boating, fishing, etc. are some of the activities you can do.
