charming_kitty, I can't reply to your PM so I'll post my reply here -- I've already committed to 929 (4 bed 2 bath, because it's the cheapest). I don't think 929 is necessarily the best or safest option out there, but it is the most convenient for me and my circumstances, since I'll be moving from CA and working until school starts.
I believe you can move into whichever available unit you want (studio, 2bed2bath, etc.) without having roommates -- you just pay your share of the rent and the leasing office will match you with roommates with similar preferences. I wasn't sure if I could find 3 roommates in time so I just signed my lease and left the roommate-matching up to the leasing office. Hope this helps!
