We stayed here and it was lovely. No the rooms aren't brand new, but they were clean, and so too was the resort.
My advise would be stay in a higher floor room rather than the gound, as the ground ones are quite dark inside and your view is obstructed by plants.
I would stay here again no problems, if only we could afford it. If you want sheer luxury, then you maybe want to try off-site.
Remember our American friends are far more picky than us, when it comes to hotel rooms, so I would take the reviews on tripadvisor with a pinch of salt.
American hotels are a fa higher quality than those found in the main holiday resorts of the Med.
