Another family and us, all with young kids, spent the weekend in Cape Cod in this property and had a great time. We were a bit reluctant at first to book this property because some of the older reviews, but they seem obsolete at this point. The fact that we booked the trip last minute, and that this house offered immediate booking, made us pick it. No regrets.
The house is simple and old (mostly noticeable in the kitchen utensils) but otherwise very comfortable and very affordable. The beds were very comfy as far as I can tell, so was the couch. The backyard was good to spend some time out, and the grill was of excellent quality. Heating was good too; the house maintained a warm temperature even when it was chilly outside.
The house is located in a super-quiet area, right in the middle of trees, which was good for us: perfect for the kids to sleep in peacefully, and perfect to not worry about them making noise within the house. Also a nice area to watch stars from as there were no lights around. The location was convenient, as it was located in the middle of Cape Cod, which made trips to anywhere a reasonably short ride.
A downside is that we somehow expected to find leftovers from previous visitors, like oil and other basic kitchen supplies, as is common in many other temporary accommodations, but found nothing. Another downside is that late departure is available but they charge you a fee (around $30) to take advantage of it -- even when it's clear that nobody else will show up -- whereas other properties won't do this. The last downside is that if you plan on having late dinner in the living room while other people sleep, the noise from the living room will certainly get to the sleeping rooms and might not be pleasant for them.
Anyway: all in all, recommended; would come again.
