I and my 5 other siblings rented this property (more like a compound) for a week. This included grandparents, multiple sets of adult kids coming and going. Most of the time the large quantity of rooms were all full. The main house is a classic New England home that is well cared for. The other cottages are basic vacation cottages, functional but not glamorous.
The rear lawn is on a bay, a nice quiet setting that was the primary hangout for the crowd with nighttime barbeques. We were kayaking right from the property although you need to time it a bit with the tides to avoid having to drag it the kayaks across the mud. Plenty of kayak exploring in the area.
We have a minor issue with the stove, emailed the owner, and the next morning a professional repairman arrived and resolved it.
All and all, despite the cost it rates a 5 star rating especially for larger groups where you really gain value. It can sleep a lot of folks with reasonable comfort and is surprisingly quiet for a location within easy walking distance of the center of Wellfleet and the beach.
