Hahha, not a bat cave :)) 🦇
Looking from the yard you don't notice it is a real cave. My friend's grandparents carved it, than her parents built a part with walls so you look at 'normal house' appearance that is attached to the mountains. But when you enter, the inner rooms are in the rock, having always almost the same temperature inside. For summer great, for winter too!
Man, it must be epic! Swimming pool?
They have it too. A small one, but have it!!
nice!
