My party of 20 had an awesome time at this lakehouse. The owner was very accommodating and helpful before, during and after our visit. The cottage itself is HUGE, easily sleeps 20 adults comfortably. To our surprise, the home was fully stocked with all amenities we could have asked for, including a beautiful modern kitchen. The lake itself is great, nice warm water in June and well-kept yards. The closest town, Tupper Lake, is only ~5 mins down the road so it is very convenient for grabbing food, supplies, etc.
The only thing to be aware of is that this is a bit less secluded that I initially thought and that is on me for not asking ahead of time. The cottage is party of 4-5 cottages in close proximity
I highly recommend this place for mid to large size groups!
