The single-occupancy bungalows go for $22-25 a night. The 3-person apartments go for $16 a night and you have your own bedroom. All are fully furnished, include all utilities and I think weekly housekeeping service. I'm planning on the 3BR apartments for a while. I'll probably move off campus at some point, but the convenience of being on campus will be nice, especially at first. The FSI website has a PDF of on-campus housing information including floorplans.
So we are at a max of $4800-7500 for room costs for 10 months. What you eat is up to you.
