This was a great experience for my fiance and my first visit to Costa Rica. It is located on a very quiet and remote location between the small town of Paritta and the fishing village of Quepos. It is on an unpaved road (about 6KM) off highway 34. You are best to have a car.
We were greeted at the reception by Peter, who was wonderfully hospitable through our entire visit. Our rooms were large and very clean, with filtered drinking water and air conditioning. I was told the furniture, dining tables, etc. were built on site by local staff. The beach is literally steps away, and most often, we were the only ones on it! Very private indeed!
The pool looked nice to me but we didn't use it.
Breakfast was included everyday of our stay and was a nice experience. They served some local foods along with fresh fruit and fruit juices each day.
The owner and his son were both exceptionally pleasant.
I think if you want to have a time away to relax and a nice, clean hotel to stay at, I would highly recommend Cocomar.
