Everything about this place is great. The location, the house, the amenities (love the outdoor shower), the price, the maintenance. I really do love it. I've stayed here twice, and will probably stay here again.
But I'd pay another $150/night if they replaced the mattresses. The beds in this house are not merely uncomfortable. They are uncomfortable to an almost intentional degree. My wife and I joked about picking up a mattress that was on the side of the road, marked "Free". I slept on the couch the last 3 nights so my wife could get actual rest. These are, with no exaggeration, the worst beds I've ever encountered in my life. They are unsleepably soft. We've had other guests with us both times we've visited, and they agreed with us. Literally any other mattress on earth would be better than these mattresses. They are horrible.
But the house is great! Honestly, it is. As long as you don't really want to sleep comfortably.
I will be back, because I like this house. But Jesus, those beds.
