I recently traveled to this house with my wife, our 3.5 yo son, and another couple with their 3.5 yo daughter. We absolutely loved it.
The house itself was perfect for us, with more than enough bedroom space for everyone and a nice big top floor where we could spread out and let the kids play. We especially loved the screened porch with a partial view of the ocean. The house was well stocked - we appreciated the cooking supplies in the kitchen and the beach room down off the carport filled with beach chairs/umbrellas and various other supplies.
Great location too - just off the beach, easily close enough for a quick walk back to the house to use the bathroom, etc. We visited Duck several times as well, lovely little town with lots of good restaurants. If you manage to find open dates for this house, I recommend you grab it without hesitation.
