There is a tour guide in San Jose this is just flat out incredible. He will take you anywhere you want to go and it a wealth of information. My friend and I hired him to take us up to the volcano (poas volcano). We went in his private car and he gave us history of everything along the way. We stopped at a coffee plantation half way up the mountain and had the freshest best coffee you can possibly imagine. On the way down we stopped at a roadside stand and had chicarones. Delicious!
He offered to take us to Jaco....... for much less than anyone else wanted. he knows the area well. We ended up not going for time restraints...... but I would recomend him without reservation. His name is Yuri Detrinidad. his phone number is 506-7043-4322 (yes there is a strange number of digits - but it is correct). He does have and use WhatsApp which is a super easy way to get ahold of him without long distance charges. The name of his company is "V.I.P. Travel Advisors" which you can google..... or even better, search him on you tube for videos of stuff he does.

This is his official business video. In the opening scene you will see a stadium where my buddy and I went to a concert, and later you will see the volcano we visited.
This guy knows all the "secret spots"...... he is lady friendly and does not judge at all. No better way to experience the country. I really cannot say enough good about him. he even does airport transportation cheaper than the taxis too.
Tell him Jesse sent you!
