In 1996 Jay the bartender at HDR told me about Hotel Plinio at Quepos.
I have stayed there many times since.
They have 3 story suites in the jungle overlooking the ocean for $110 (negotiable).
You are literally in a giant 3 story treehouse with exotic wood floors and walls, huge trees supporting the whole structure. the whole front is screened in.
You are in the jungle with tree frogs, sloths, exotic flowers just inches away.
Excellent pool
First class restaurant.
Here is the link have fun.
