We stayed at Windermere House in October. The property and surroundings are beautiful, with obvious attention to guest comfort and convenience. We were treated wonderfully by all staff we encountered. Had we stayed longer than two nights, we would have used more of the many recreational and comfort facilities available. As it was, we enjoyed great meals at the restaurant (best apple cheesecake I've ever had) and pub, a lovely paddle on the water, swims in the pool, sauna, and my wife had a massage at the spa. Our room was spacious, clean, and comfortable with superb views of the lake. There was moderate sound transfer between our room and the adjacent room, which is connected by a door between them. Our neighbors were not loud nor annoying so no issue for us during our stay.
We would certainly plan another stay at WH if visiting that part of Ontario again. Loved it.
