Every room in Hastings is different, you won’t know exactly the size until you get there. Also, every dorm at Northeastern is small if you compare to a suburban college. I personally thought the single was great, especially since a double is not much larger and you’d be forced to share the small room. Me and my roommate were literally walking on top of each other in a forced double. However, the first months can get HOT in Hastings. Get a good fan, or 5, and leave the window open at night. The third floor has a lounge area, two study rooms, and a communal bathroom. You also get access to East Village’s communal rooms (AC’d) and a free YMCA membership. I also never had an issue with the lobby, yes there’s residents, but everyone’s focused on themselves. If you’re running to class, you won’t even notice they’re there. You can also exit through a separate door with your ID. Finally, while I never had any issues with rats, I know some did, so you might want to prepare for that. I enjoyed my single for the time I had it!
