Just south of Hermosa is Esterillos beach. Check in with Rick to see if his condo is available. It's set up and is on the beach in front of the break. He owns the surf cam for Esterillos on Surfline. Super guy, fun waves everyday. Hermosa is more top to bottom wave but this place has a variety of waves close together. Just talk to Rick. He can help you out. His website is pretty thorough.
Oh, and get a GPS when you rent the car. I found that invaluable and my wife loved her new toy. http://www.costaricajewell.com/Ester...Costa_Rica.php
And it's about 2 hours or less from San Jose. Easy drive down.
