Hahaha, could be - experiencing it, as if I would stay longer and they close the doors of the museum, I would have to sleep there in that bed 😂
I would even have to mill the wheat to have flour and prepare my own bread. 😆

The rock wall is cool. Not sure about the cleaning though.
There are houses in the mountains with rock walls and one of my friends has a "half cave" house. The inner rooms are basically in the mountain and the other part of the house looks like a normal building. Perfect insulation! 👌
