"We have just left the hotel this morning and we was sad to leave! everything was perfect, the staff, room, food, pool, even the security men outside! everything was amazing, the location of hotel was perfect for us we hired a car to get about which the hotel helped organise, we didn't want to be staying in the busy areas so this was nicely tucked away with its own beach. We will happily return here next year ❤️"
