I've lived in the Conover Apartments (grad student/family housing) since August and can answer any questions about them. Since I was moving from relatively far away, I didn't search for apartments in Newark - I signed up directly for the grad student housing. They were all completely renovated last year and are quite nice - I was afraid they were going to be like dorm rooms, but they're a little better! There is carpeting in the bedroom, and all the floors, bathrooms, and windows are new. There is heavy-duty fire and security protection, which is nice. Parking is expensive (over $400/year) but you'd be paying to drive and park if you lived off-campus anyway. The location is convenient, as it's a very small campus. My neighbors are all very nice, but I can't say anyone here has formed a community.
Newark - well...it's extremely small, the restaurants are terrible, Main St is underwhelming, and the rest of the town is tired worn-out strip malls..but hey, we're here for education, not the quality of community life, right?! The campus is indeed pretty - sort of less opulent version of UVa.
One of the best things about Newark is its location. As I mentioned, it's small, so it almost feels like living in the country - but major cities are nearby, and there is plenty to visit within a couple of hours' drive - including the beach. There is 1 person in my program without a car, but I don't know how she does it!
Feel free to contact me with more questions!
