Send a PM to Chloe for rates....ballpark 200 per night.
Hard to tell number of guests as it could, and does, vary from day to day. We were there in July and there was just one other couple.
Not sure if Chloe and Thierry are naturists....they were always clothed during our stay, but they are two of the nicest, warmest, kind and caring people you will ever meet.

I would highly recommend Club Fantastico.
