Recommended - we had a lovely week
You never know what kind of environment you'll encounter when you arrive--is this a cabin city or a standalone hut? Fortunately, Hazel and Mike communicated very well in advance, with suggestions on directions, arrivals time, where to park, bring a towel and flashlight, and so on. They were ready for us when we arrived, giving us a tour and explaining the facilities (which were also documented in a greeting book).
It's a roughly 12x12 cabin with electric lights (and places to plug in your phone, though cell signal isn't great) and a gas stove with kitchen amenities. There's a water tank on the counter, the bed is comfortable. The sink and shower are against an outside wall, just a few feet from the outhouse (yes, composting toilet, well-maintained).
The cabin is charming and cozy. Screened windows worked to keep the bugs out (we never closed them) and fans worked to keep it cool. There's a wood stove we never used; we were provided plenty of blankets. Our hosts were happy to introduce us to their gardens and animals, and even chat about how things work. It's located just a few minutes from amazing lobster and very nice hikes, and 20 minutes or so to several towns with great food, galleries, and/or hiking.
We stayed for five days and never ran out of things to do.
