A huge chunk of my class lived at Reed Luxury Towers
) I would say 80%.
It was not bad and very-very convenient. Try to get into a suite, not the singles at West wing. Plus you will meet everybody, will have a chance to find roommates for next year and you will wake up 15 min before lecture and still make it. Plus there are tunnels that go directly from Reed to SOM, so you can be in yr pjs and avoid snow/ nasty weather.
If you want to live in an apartment check out cragslist.org for Baltimo' and Hopkins Gazette (spelling?), students are always looking for roommates or sublets. Areas that are convenient if you do not have a car: Mt.Vernon and Homewood (find something close to shuttle)...
