2 adults, 5 kids had plenty of room and plenty to do at this beautiful home.
Haley Pond was perfect for kayaking (and kayaks, paddles, and life jackets were all available!). The location is excellent—it feels private, but not isolated; and we could walk or kayak to town for ice cream.
One thing to note is that, while Haley Pond is wonderful for swimming (clean and cool, not cold), entering the water isn't so easy. The dock is in shallow water, so you can't jump in; and the bottom is covered with slippery, algae-covered rocks, so wading out to deeper water is difficult and not so pleasant. Best bet, we found, was to jump out of a kayak.
For a rental, the Boucher house's kitchen is remarkably well equipped—mixing bowls, small appliances, many pots and pans (could use a second sheet pan), grill utensils, popcorn popper, decent knives, spices... For that matter, the whole house was well equipped: a selection of games and puzzles, electronics including Wii, horseshoes, fire pit, guide books and maps.
We enjoyed our time at Boucher immensely, and I'd recommend the house without reservation. Furthermore, Morton & Furbish are a pleasure to deal with.
