My book club stayed here for a long weekend, and we couldn't be happier with our experience. Our only complaint was that we didn't have more time!
Overall, the house is perfect for a large group. The hot tub was nice and the dock was in great shape - plus they provided lots of floaties, chairs, and towels. The kitchen was one of the best I've seen in a rental - there were lots of tools and utensils. I do wish there would have been more large bowls, because we only found one which we had to wash for nearly every meal.
Some things to note: There's not much phone signal (at least for T-Mobile, which impacted my ability to contact the host because they texted rather than going through the app), but there is fast wifi. A few of the beds are a little stiff, but there are plenty of pillows and blankets. The upstairs got a little warm, even though we had the AC on, but there are multiple fans that helped. The walk to the dock is short but very steep, so keep that in mind.
Would definitely recommend!
