Well busing gets expensive, Loyalist doesn't (or didn't) offer free bus passes like St.Lawrence in kingston, I went to both and the no bus pass thing was a real pain.
There are alot of amenities at the college, the Shark Tank is a great pub, there is a Tim Hortons (critical) and a fairly good gym. There is also a reids dairy (ice cream castle) for all the women in the class when they flunk some exam, its a short drive away.
There are apartments in Belleville, but..eh..alot of them are crap. Belleville has gone down the tubes in the last 10 years, there is becoming a real drug problem, crime is going up, or at least appears to be, in some areas. Can't leave anything unlocked or open. They will wrench open your hood to steal parts from your car if they think they can in some areas.
There are a few good clubs to go to, not a giant selection or anything mind you. Night life is there but it isn't as good as a big city, but it isn't as bad as a small town either. There is a mall, but its kinda..well, its a small city mall. There are a couple other crappy malls which don't even warrant a mention.
Also note: Tweed is about half and hour to forty minutes away driving. And Belleville is a small city not a small town, its about 45-50,000 or more depending on what you count. Quinte West and Belleville kinda merge..but keep out of Quinte West (ie Trenton), that IS the slums.
