We spent 4 nights at Otter Lake while sightseeing the Pictured Rocks National Park. It was a nice quiet place, the owners went out of their way to welcome us. The bathrooms and showers were very clean. The location is about 10 minutes from town, but that wasn't a problem. It's a great place to spike out from or stay there the whole weekend. The lake seemed very nice even though we didn't use it.
I would definitely stay here again.
