I booked the Lago House for a holiday trip with a group of 9 adults, and we were so impressed by the size of the house — we all felt like we had our own space while still having the chance to hang out in the two generously sized living rooms, and could share meals together at the huge dining table and open kitchen. Since we were there in the winter with snow on the ground, we didn't have as much of a chance to use the backyard, but it's huge and would be amazing in the summertime (same with the two deck levels). We did get a chance to use the hot tub on the lower deck, which was awesome. The lake is so quiet, and the area is removed enough to feel peaceful, while still being accessible to local amenities.
We had an issue with heating in the living area of the house upon our arrival due to the recent deep freeze in New York, but Troy was extremely responsive and helpful, and had maintenance technicians sent out immediately to rectify the issue. He was kind enough to check in several times to ensure we were comfortable once the issue was fixed.
This is a wonderful rental for a large group or family, and I'd definitely book it again if we return to the area in the future.
