I spent a week here alone and a week with my wife and kids and heartily recommend this house. It's about a mile or two away from Wellfleet Center by car or bike and you can avoid Rt. 6 for much of the way, if you like. The house is far enough from Rt 6 so it's quiet and pretty much is surrounded by woods. You're also about a half mile from the quiet relatively undiscovered Duck Pond and have easy access to the Ocean beaches.
The house was well cleaned and equipped with beach chairs and boogie boards and well stocked with kitchen equipment. The three bedrooms are roomy and comfortable and there's a TV room separate from the living room.
The owner is quite attentive. He called to check that everything was OK once during my stay and once after, and was eager to address any problems, though I didn't really have any.
The outdoor deck or kitchenette would be cramped for any more than five or so people to sit, but for a crew of about that size, the house is a good fit.
