Gorgeous location, and the cabin was beautiful inside. As previous reviewers stated, all the beds are very much on the firm side. Overall it was a great stay, mostly because the environment inside the cabin was so nice. We really enjoyed the indoors and the view. It's been a very rainy summer in Wisconsin, so as of mid-July the mosquitoes were horrible outside. Even with deet bug spray they swarmed us the second we stepped outdoors. We were not able to use the firepit at our mid-July stay, and even being down at the dock was a challenge....but given our weather, I would not assume this property is always so buggy in the summer. It's possible we just had back luck. We did get out on the kayaks, though, and that was fun.
As for suggestions for improvement-- the cabin is in need of a look-over in the kitchen. New glassware, a new set of mugs, a larger frying pan, large cooking spoons, etc. We managed, but what was supplied for cooking and dining was sometimes pretty slim. The large electric griddle for pancakes was appreciated!
We stayed at the cabin during a very hot, muggy stretch of three summer days, and the AC did a great job of keeping the house cool. I was surprised it was so effective! It had to be running full-blast most of the time, as it wasn't a whole-house unit, but with the rest of the air in the house circulating through the forced-air system, the AC worked beautifully--even for our kids sleeping up in the loft.
We would stay here again, especially since many of our planned outdoor activities were at local state parks and in the Dells. There wasn't a need to spend a lot of time outdoors while at the cabin.
