One thing is that I don't like those places being in between, places like Si Como No. There is a long walk to the beach from there, you will probably have to cab it. And because cabs going from Manuel Antonio towards Quepos are required to charge a very low rate finding a cab to take you in that direction can be difficult so you usually will have to call one and then wait 20 minutes for it to arrive. I stayed at the Hotel Verde Mar and it was a great location, literally could stumble out of bed and be in the ocean in 2 minutes or walk down to the village in 5 minutes. The hotels like this one in the middle require a little more work getting around.
