We have stayed at many rentals along Lake Michigan for the past 12 years, and there is one that we stay at yearly. "Endless Lake" just tied for our favorite. We plan to return! Layout is great for a 3 generation family, and amenities were perfect...there wasn't anything we wished we had. We stayed in January, so can't speak to summer "needs", but I'm sure all would be fine.
Lake view fantastic, large property for playing or campfire (yes, even in zero degree night temp we had 2 mini campfires using paper starter logs supplied onsite), large dining table, lots of furniture (altho my husband wished there had been an easy chair upstairs..too bad!), comfortable beds, super cozy bedding (Amy provided flannel sheets...with winter design!!), all kitchen tools and large/small appliances, plenty of dishes, flatware, glasses, well heated, really nice towels (yea).
Amy was wonderful in initiating or responding to communications ( it was better for me via cell phone vs vrbo emails). she was polite, quick, and helpful; I try not to bother hosts, but i contacted her a bit more than normal, and she was gracious. We had excellent wifi, etc---no switching of time zones across lake, either.
For those renting in summer, the erosion that has happened along the lake is devastating. Don't complain there is no private beach---just be thankful that Amy's home is still safe, enjoy the gorgeous views, and have a marvelous time!
