Rainbow Ave is hit and miss. Decent bldgs next to low rent bldgs intermingled with problem bldgs. Put it to you this way, most people keep their bicycles inside their apts, not padlocked outside. Always lock your car and don't leave anything valuable in it or visible. Covered parking is sparse mostly. You better be OK with stairs. It all comes down to what you're looking for. 

Check with Redbird Property Management on Linden St, Normal too. Good people. They have or manage the whole spectrum from low rent, to typical, to high security downtown lofts, to commercial property. They also manage some Rainbow Dr bldgs. Tell them straight up what you're after &amp; rent $ range. Worst that can happen is they don't have something right now to suit and will recommend or refer you to someone trustworthy.

Oh yeah, Welcome to Bloomington/Normal, in advance. Pretty sure you'll like it, esp after the pandemic craziness fades.
