The campus is aesthetically one of the best, in my opinion - that is, when the weather's nice. I'll be a sophomore in the fall and I can say that it's really windy during the winter (or at least it was this past winter) - but it's truly beautiful during the fall and the spring. And, of course, it has its moments during the winter too.
Unfortunately, I think that the town of Geneva still leaves much to be desired. I can really count on my one hand the number of times I've been downtown during the school year. There are some really nice restaurants and good little shops, and as long as you stick to the downtown area you'll be fine. But I'd advise against going there at night, or going into some of the residential neighborhoods of Geneva - they've definitely seen better days. In addition, I think that there used to be some kind of pseudo-bar that HWS students frequented until it closed pretty recently, so going out to town for the evening isn't something that's done very much. The relatively affluent status of most of the kids going to HWS and the relatively poor town of Geneva don't always get along too well - I think there's some town-gown resentment, which is to be expected in a lot of small college towns.
The campus itself, though, is very safe. I've never felt threatened or anything, even walking by myself at night. Campus security does a very good job of patrolling the area, as does the Geneva PD. Most crime-related incidents happen off-campus, and I don't think that there's any reason to be overly apprehensive about crime.
Personally, I was pretty busy with my studies for most of the year, and I'm not one of those students who celebrates a five-day weekend. But even for me there were times when I was looking to go out on a Saturday night, only to find that there really isn't anything going on. Campus Activities tries its darndest to get good acts for the school, and they succeed now and then, but, this being a college, students sometimes just want to go out to parties. It's really up to the few fraternities on campus to provide the parties, although those are naturally watched carefully by campus security. I get the sense, though, that the administration sometimes turns a blind eye to them, since they know that if it wasn't for the frats there really wouldn't be all that much to do on weekends.
