You should book this house. For a week in July, we had two 75 year olds, two 45+ year olds, and 4 kids between 12 and 18. Cannot imagine a better place for a crew that size. The 4 kids had a blast in the bunk room, which in theory could have slept 2 more on the trundle beds. We ended up not even using one of the bedrooms. Common areas were huge. Owners stocked house with great books about the area. We spent many afternoons and evenings in the spacious and shady back yard and on the porch — including one entire day when we were worn out and just needed to chill and hung out at the house reading, playing badminton and croquet, etc. All rooms were comfortable and well stocked with pretty much anything we would have wanted. Having never visited the area before, I was worried that the house would be far away from the town and the resort. Neither was a problem, at all. Sun Valley and Ketchum are small, and simple to get around. We had a car., which made things simple, but it was an easy walk to town as well, less than a mile. The (excellent) bike path is just a couple of blocks from the house,, accessible by foot or one of the three bikes the owners provide. Owners were proactive, reaching out when we arrived and quick to respond when questions arose. And compared to rates elsewhere, this place was a steal. Basically, if you are looking for a house for a big group over a week or more in the summer, stop looking. This is the one you want.
