We found the whole experience of staying at Shell Road a breeze. Finding it was simple as it was close enough to Watsonville for supplies, etc but far enough away that it was secluded.
The apartment was beautifully decorated, had every facility we could need and was so close to the beach it made it impossible to resist going out just to dip our toes in the water and enjoy the sea breeze. Quite often we'd sit with the doors open and the curtains pulled just to hear the ocean while we relaxed.
5 star in every way. The only down side was having to leave, we'd have happily spent another week achieving total chill there.
