We stayed here for four nights in July 2010
Highlights - very clean rooms, great air conditioning, a bath, good shower pressure, lovely pool, right on the beach, free wifi, pick up from the port. Gorgeous flowers all around the rooms too. There's a shop with all the bits & pieces (toiletries, food) you'd need and a restaurant with good food at reasonable prices. There's also facilities to wash clothes. We didn't do it, but there is windsurfing or scuba diving on the beach too.
Lows - none really other than it's a bit out of Naousa (sp?) but there is a free bus from the camp site or the public bus
I would definitely stay here again & so would my four travel companions!
