I stayed in Chez Carole with my wife. To say we enjoyed the vacation is to say nothing. It was excellent - the staff is very friendly and helpful, the design of the rooms and bungalows is great - you entirely feel you are away of the city rush, crowds, noise, etc; just you and nature! The beach is so close and it is very cozy. The terrace of the restaurant has a mesmerizing sea view, the food is super tasty, portions are big, and the prices are very affordable! You also have a swimming pool, spa, small gym; you could also rent a motorbike directly from the reception, so you can travel to the Duong Dong town or to the north of the island, since it's all pretty close.
If you are looking for a quiet and peaceful holiday away from noise and crowds - Chez Carole is a perfect option. It's great for families with kids as well. I will definitely come back there.
