We stayed for three nights in late August and had a lovely (hot!) beach vacation on Park Point. The location, proximity to the lake and beach, the views from the living space and deck, and the off street parking were all very much appreciated. The in house amenities and basics provided were sufficient, though a couple additions (coffee, sugar, creamer, basic set of cooking spices, though we always bring our own just in case) would make it feel more welcoming.
The spaces for sleeping are sufficient and nothing more. The beds were sufficient, though not very comfortable, but that's very personalized. The loft bedroom was great for three teens to have their own space and half bath; the tight spiral stairs definitely limit who can use that space. The bathrooms were of a good quantity, but dated and tight. And the kitchen has what you need, but is dated, dinged, and is showing its decades of wear and tear. As others have said, with hotter days happening more often, the two small AC units struggle and ultimately don't keep up, especially in the loft and bedrooms. Thankfully nights were cool and we were able to stay comfortable by opening windows and using the ample tower fans to circulate the air.
All around, the interior is 3-star and needs some investment to make the interesting and beautiful open architecture shine. What saves the place is the architecture, location and views and they're such that we'd return.
The contract you have to sign is imposing; I've stayed at dozens of properties and this was a first. But the owner had great communication and was flexible with our group size being in flux up until our stay.
