We are a family of 5 and we could fit in with the youngest on the couch bed in the living room. The view is amazing and the heat was okay due to shade and wind from the lake. The neighbors are kind.
The Wi-Fi is not great for streaming and we had to park 100-400 meters from the house.
We had hoped that there was a short of beach by this lake - there is not. But there are places with public pools and with entrance. We used those several days.
All in all we had a great week!!!
