We stayed at Wattana for 4 nights in January. It was the perfect little place with its own secluded beach. The bungalows were fairly basic but still very comfortable. The staff was very attentive and welcoming. They also offered taxi service, laundry service, motorbike rental, WiFi and a restaurant all on the premises which was nice because the resort itself is a bit out of the way.
The only downside was there was litter in the sea in the mornings when the tide was high. Also, careful of the step down into the bathroom - it can be slippery when wet. Overall, a great little place for a quiet, relaxing vacation.
