This was a cute, clean, and mostly comfortable place to stay for our night on the island. Would definitely recommend for short stays or as just a "home base" for being out and about on adventures most of the time.
However, there are a few less-than-desirable features that weren't totally obvious to us from the listing.
First, the bathroom has a "composting toilet," which is a bit smelly and complicated to use relative to a standard flushing toilet. Something of which to be aware.
Second, everything is in miniature - the shower is tiny, the kitchen stove is tiny, etc. It's all very cute and again perfectly serviceable for short stays, but you might find it lacking if your plan is to have a guest over for a big meal or something.
Finally, the cottage is located right in the backyard and eyeline of the hosts, so you're not going to get an optimal sense of privacy. There are curtains and blinds that can be drawn at night, but if your hope was to sit out on the stoop, you'll be standing in their yard (probably in the company of their very sweet yellow lab). Again, not a deal-breaker for us and the kind of trip we were having, but something to keep in mind.
All in all, though, again, this is a cozy and well-kept little spot. We enjoyed our one-night stay, but might look for a place with a flushing toilet if we visit the island again for longer.
