We stayed two nights at Osa Mountain Village when we were checking out its sister development - Serenity Gardens Eco Village. We had a very comfortable cottage right near the zip line (it was fun watching adventurers "zipping" by our veranda). As mentioned by others, the staff is excellent as is the food. There was a dinner served one evening that many of the permanent or semi-permanent residents attended which gave us a great opportunity to learn a little more about what it's like to live at OMV as well as Costa Rica in general (there were no complaints!). Having earned my Permaculture Design Certificate here in Colorado, I was especially impressed and intrigued with the gardening project at OMV. Some of the residents and several volunteers are involved in producing organic food for the village and it was cool learning about the many fruits and vegetables that can be grown there. OMV and Serenity Gardens Eco Village both have the potential for becoming self-sustaining communities.
