We rented this house for a week in August for a family reunion -- three families with teen or college-aged kids. The best things about it:
Able to accommodate 12 of us comfortably at the dinner table!
Lots of different "hang out" areas, so people were not on top of each other all the time. For instance, you could have people doing a jigsaw puzzle on the screen porch, hanging out in the living room, swinging in hammocks in front of the house, gathered around the outdoor fire pit, playing ping pong in the downstairs rec room, and reading on the deck off the master bedroom -- all at the same time.
Secluded woodsy location. We felt like we were far away from the rest of the world, even though we were a two minute drive from Highway 6, the main route on the Cape. You can hike from the house directly into the wooded trails of the National Seashore. In fact, you can hike along a dirt road through the National Seashore and then along a quiet paved road to reach a beautiful ocean beach (about a 20 minute walk).
Close to Wellfleet and Provincetown for shopping, bike rentals, etc.
Well equipped kitchen. (TWO lobster pots!!) All the utensils we needed for cooking, and we are a family that likes to cook.
The screen porch is a great place to hang out.
The only cautions I would give:
This is NOT a luxurious, Architecture-Digest-type home. It is more of a casual, lived-in type home. For us, that was fine. But if you are looking for a rental that jumps out of the pages of a design magazine, this is not it.
The two main bedrooms are great. The third bedroom suitable for a couple has a pair of twin beds that can be pushed together. It is adequate but not as nice as the first two. So if you have three couples, be aware that there may be a little tension in your group over who gets the two "better" bedrooms. :-)
Other than that... wonderful house! Wonderful location!
