The massage school is on the outskirts of Ithaca (a beautiful setting, right on Lake Cayuga, just gorgeous site). There isn't much around there, and there really aren't any sidewalks or anything as I recall. (I don't live in Ithaca yet, but have visited many times.)
Because of the school's location, you would most likely need a car. Or check the bus route. Ithaca has a bus system (very inexpensive) that's very good. Since the hospital and a museum is out that way, the bus route probably goes that way. You may want to click on

Have you searched this forum for info? I assume you've looked here:
Finger Lakes School of Massage: (http://www.flsm.com/student_life/housing.php - broken link). Have you asked the school for housing referrals? Have you checked craigslist? There are dozens and dozens of apts listed in Ithaca on craigslist.
I think I posted before that I seem to recall an apt complex about a half mile or so from the massage school, on the other side of Trumansburg Rd (aka Rt 96).
As for bad areas of town, someone else will have to chime in here. I've been going to Ithaca about six or seven times a year for the past four years, and I haven't seen any "bad", high-crime or scary areas, but I may not know the town that well (but I'm from Chicago, so my idea of a scary area may be different from someone else's). As I've looked at real estate there, neither my friends nor family in Ithaca have told me about any areas to avoid. But again, someone from Ithaca should chime in on this.
