It was so great to find a home that could fit the 16 of us and I'd definitely recommend this house.
Some highlights: The different wings of the home allowed some folks to stay up late in the game room/basement apartment while folks upstairs slept soundly. The three kitchens meant we could have a designated GF kitchen for a family member with celiacs. It was a relatively short drive to Glacier NP, Whitefish, and the Glacier Airport. When we ran into trouble with our flights, the owners very kindly granted us a late check-out.
Some things to be aware of: It is located right on a busy road, so you'll hear trucks and cars flowing by. (Fine for us city folks.) There are a lot of stairs to get into and around some of the bedrooms, and so I recommend carefully thinking through where you'll put your great aunt vs. where you'll put the louder kids or night owls. (We personally put older folks on the main floor—up one sturdy level of stairs—then the youngest folks on the top floor with the spiral staircase. The night owls stayed in the basement next to the game room.) Lastly, what we paid for 5 nights was obviously a lot because of the mid-August peak season but I was sort of expecting more in terms of little details like toilet paper, and maybe nonessentials like coffee and firewood. So just a note to visit the house and take stock of everything before heading to the handy 24-hour Super 1 shop, just a few minutes away.
