This is a clean, extremely quiet, very dark spot a few miles outside of Coudersport.
Listing is completely accurate - it has five bedrooms that easily sleep ten total adults (or a few more if toddlers are involved). Kitchen is well maintained and includes all usual items (pots and pans, dishes, silverware, a few mugs. I recommend bringing paper plates and cups, because otherwise your hand-washed dishes will exceed the space you have to air dry everything.
The cabin is on a little gravel road bordering on a state forest, which provides for a very tiring hike straight uphill for a long way (I'm not sure exactly how far - it's very tiring). Or, as advertised, there's a cute little creek a few feet away. Never saw any fish, but it's a great spot for foot dipping on a hot summer day.
There's also a campfire spot and a shed fully stocked with firewood - perfect for s'mores.
And, at night, you get the real benefit of being in the middle of nowhere - the backyard is impossibly dark, and after a few minutes for your eyes to adjust, you'll see more over your head than you ever believed possible - so many stars, the Milky Way, passing satellites, a meteor every few minutes. We even saw the International Space Station zip by once! All this is true even if you have a campfire roaring - just don't look at it while it warms you.
If you run out of anything (towels, toilet paper, etc.) the owner responds quickly. I didn't have anything more serious occur while I was there.
If you really, really, want a negative, the WiFi internet connection through what I think is a satellite feed works but is slow. But, if you're coming here to work, you're totally missing the point. Come here to get away from it all instead.
