We stayed here for a week, and filled up all 5 bedrooms. Functionally, everything was great - the three bathrooms all had hot water for every shower, kitchen worked, internet worked, and the owners responded quickly to any question we had (what's the internet password, how do we get to the swimming hole, etc.). We were able to all fit at the dining room table (including one night with 10 adults, two toddlers), and other times ate on the deck.
The view is great, looking out onto the mountain range, feeling very secluded. At night there is plenty of clear space to view the stars.
The toddlers had fun outside, with plenty of room to run around. We enjoyed a few fresh blueberries and raspberries.
Within about 30 minutes of the house, there was Clark's Trading Post, the Lost River gorge & caves, Loon Mountain, Echo Lake Beach, various lookouts and trails at Franconia Notch State Park (The Basin and Falling Waters trail were popular with us; the Basin in particular was suitable for the 2 and 3 year olds), and it was a one hour drive to Storyland.
We'd certainly recommend this place to anyone looking to get away with a bunch of friends & family.
