.... if they are really really cheap, I can see this as an option for students. I had trouble renting even a 10 sq meter closet to live in when I was a student. There was a serious lack of housing in the area.

I ended up living illegally in an abandoned warehouse and paying the owner a rather expensive amount in rent

On the other hand, knowing the kind of people who come up with these ideas, they are gonna market this as some boutique shit and charge hideous rents...

BTW, if this creeps you out, you should google capsule hotels
