Katherine's place is in the perfect spot in Redondo Beach, CA. Her hospitality and responsiveness were great, too! The amenities are solid especially the hot tub and outdoor grill.
Couple things I would point out:
The wi-fi is apparently turned off at night and is turned on every morning. If you are an early riser to hop on an eastern time zone Zoom, you may or may not have wi-fi.
Whatever you do, please, please, please refrain from saying anything related to Airbnb while out in front of the main house. I was shhhh'd and sent a nice reminder from the host. If it's being done on the down-low, totally understandable. Maybe just add that to the check-in instructions.
