As someone who did the exact same trip to Nosara twice, I understand why your friend wants to go back. My first trip was 10 days, and the return trip I stayed a whole month. Both trips were in the rainy season but it actually didn't rain all that much during the day. I had the same airbnb in Pelada both trips and could walk to Guiones or the little point break in the village. Or you could drive north to Ostional for a more challenging wave on a black sand beach. Great diving and fishing nearby too. So much to do and explore. Pleada is simply paradise for surfers looking for a low-key get away.
