@Peter3354 It does take about 24 hrs for listings to go live.
But I don't really understand what you are renting. Just a place for people to throw down their sleeping bag and have a shower? Are people supposed to sleep in just a sleeping bag on a wooden platform with no mattress? Is there any counter space to prepare food? A table and chairs so people have a place to sit? You don't have photos of the bathroom, shower, or the rest of the cabin aside from the sleeping platform.
I'm not sure how you foresee guests using these cabins- why would they pay to stay there when they could just as easily sleep in a tent, considering there isn't any sort of kitchen?
