Yeh its always obvious in hindsight. They are designing it for current time. i.e. they have common kitchen so if there is a problem of dirty dishes then they will have someone cleaning up the place daily or weekly. No question of who pays the utility bill because its included. This is very different from just renting out room. They may also have someone loosely policing the place in case there are issues in common living area or someone is not behaving properly.
