We usually stay at Best Western in Jaco because it is right on the beach. So I would say that while the Mar De Luz is very nice ( for Costa Rica ), We use this as a Great 2nd Family Option.
If the beach access is not an issue then they are equal.
You must know that Costa Rica has different standards than the USA. You cant compare the two.
So , for Costa Rica, this is a nice family place. I gave it 5 stars.
