We were out and about (from Anna to Horseshoe Lake to Mounds) so didn't do much more than sleep there. Comfortable and quiet. Wifi is weak (coming from a marginal cell signal), but why are you in a cabin in the woods if you're going to binge Netflix? Our reservation didn't get to the owners before we arrived for some reason, but they quickly prepped the place while we waited. They were very friendly and helpful.
As others have mentioned, GPS gets the location wrong. The mailbox description was obsolete - we pointed that out to the owners, so it should be updated now. We figured out the location using Google satellite view and had no trouble.
