We were incredibly happy with our stay at Mike & Colleen's cottage. The listing is even better than it looks in the pictures. It's wonderfully cozy without being cramped, and spacious without feeling empty. The kitchen is well stocked with the basics. If you're coming with a large group, and plan a lot of home cooking, make sure to bring a few extra bags, tupperware, etc. It looks like the stairs down to the river had been redone recently - they're very nice and an easy walk. The view from the back yard is wonderful. Access to the lake, Au Train, Munising are all super convenient.
We highly recommend looking into a pontoon rental to check-out Pictured Rocks. We got perfect conditions on a half day rental, and even got to explore a sunken ship from the 1800's!
Mike and Colleen are great communicators. The house was perfectly clean and easy to access with no unwanted surprises.
Good luck and enjoy your vacations!
