Tons of nostalgia here from my childhood, as my my grandparents had a similar sized farm and I had many fond memories there growing up. We stayed 3 nights and drove up to voyageur national park two days. Overall a great place for two families with young kids vacationing together.
Only two considerations for other travelers from my perspective. First, while it easily slept 4 adults+6 kids. Given the focus of our activities requiring bathing/showers every day, we were very short of hot water and had to be very strategic with scheduling our hot water use. Second, there were quite a few mosquitoes in the house even from the beginning, especially in the bathrooms. We quickly learned to keep the bathroom doors closed at night.
