For the people who need or want to be in the city and can't afford anyplace else and don't mind living in a shoebox and sharing a kitchen with others, then this just might do. Perhaps I am too old to enjoy the urban-chic spirit of these places, but they don't have much of any spirit to me except $$$ for the smart developer who can pull this off. Congratulations for finding your (tiny) niche.
Ahhh - density! This is living!
