This would be a fun place to visit and explore!
It's probably so beautifully cool down there. I would want to come up with a way of channeling natural light down there and "amplifying" it somehow (mirrors?). The constant artificial light would bother me after a while.
I think light tunnels would be a good solution to this problem!
