We visited in early April to see the solar eclipse. The house was cozy, cute and comfortable, the kitchen was very well equipped, the views of the lake are lovely, and the eclipse was spectacular. The property is clearly optimal for summer use, and in early spring we couldn't take advantage of all of its amenities and advantages. Would love to come back sometime in warmer weather.
A couple of things to be aware of: It's a long and steep set of stairs from the parking area to the house -- definitely not for anyone with mobility issues or difficulty carrying things. The road is very quiet, but there's an active train line just on the other side, so there were occasional loud train whistles at all hours.
