First, on the plus side, the house is in a nice quiet, private location (there were a lot of motorboats, jet skis, and water skiers, since the house is fairly close to Holderness, but they were across the lake). It was great to be so close to the water. There is a nice big covered porch overlooking the lake, where we spent a lot of time and had all our meals. The dock, diving float, and shoreline provided really nice access for swimming, and the water was beautifully clear and clean.
Unfortunately, I don't think the house has had a deep cleaning in a really long time. We found trash under the bed, a broken lamp and broken headboard in our room, and mouse droppings in the kitchen (including silverware and plate areas). The house is quite dark, which is to be expected in an old house with dark wood panelling, but also generally dirty, dusty, and full of cobwebs. We were disappointed, too, that the sunfish sailboat had broken rudder fittings, which couldn't be repaired while we were there.
The owner was very nice, and helpful in providing information on area activities, when we called and spoke to him on the phone, but there was not a lot of this information in the house.
Our family had a nice week, and enjoyed being on Squam Lake and spending time together, but for us, anyway, the lack of cleanliness was a real drawback.
