No window in the bedroom
You have this room if your roommate sectioned off a corner of his massive one-bedroom in order to have a roommate so he could afford to live in a luxury building. Unfortunately for you, you now live in a cave with zero ventilation. But at least you’re extremely warm in the winter!
A bedroom accessed via another bedroom
A “railroad” apartment means you're walking through one room to get to the next. And if any of these rooms have real doors, then consider yourself lucky. But, honestly, what a great way to bond with your roommate! There’s really nothing like being woken up by another person's middle-of-the-night bathroom trip to bring two people together!
Realistically, you’ve probably only nearly knocked yourself out two or three times TOPS when trying get your bed out after a night of drinking, and the space you save when it’s tucked away totally makes up for the fact that you don’t have any kitchen/bathroom/living room/bedroom space (which again, you’re in no way bitter about! New York is a great place to live, Mom!!).
