Mer et Soleil has a beautiful location looking over the sea. However the villas were ill equipped and their age showed in some ways. Some lights didn't work, wifi was spotty, (even after being fixed) plumbing issues (the toilet stopped flushing at a point), lack of adequate cooking utensils (we only had a bread knife for cutting!) . We were also incredibly cold but not comfortable with using too much electricity as each kilowatt was charged extra... something we were only told on arrival.
However Fabian/Laura were very accommodating and did not charge us for electricity. Overall I would suggest this place is better in the summer when the weather is warmer. But should try and be better prepared for the winter season!
