There are several agencies with which you could book, in addition to the airbnb & co. I did booked once through makemyvacation.com for a week and found availabilities for other appartments through Airbnb for shorter periods. I was not disappointed by the complex and i'm planning to go again next year.
I did vrbo myself, worked out great . If you can afford it do one of the oceanfront units awesomeness!
They have many agencies and a whole bunch of the owners. I would suggest visiting their website https://www.north-coast-village.com/
