This house is in a great location, close to Lake Geneva and the lakeside towns. The owner communicated frequently and answered all of our questions. It was a good fit for a family on vacation.
The only recommendations for improvement I have are regarding things structural to the house. For instance, there is no central AC so you must keep the windows open. This is fine, except when storms come through, as they did 2 of the 3 nights we were there. The windows just swing freely so strong winds slam them shut and wake you up. Also, there is no clothes dryer so you must hang up clothes to dry after washing them. This is tough when it's raining. Finally, there are no towel racks anywhere in the house, which is unusual and annoying.
Overall, however, despite these odd features, we really enjoyed staying in this house.
