So, as it turns out I'm not taking EITHER apartment.
#1 rule of any online transaction = Google everything about everyone.
I Googled the username of the person I was getting ready to sign a contract with, and Google kindly led me to this:
If you can't actually read it clearly, it's some creepy guy looking for a WIFE! Ew! Ew! Ew! He also had a profile on some other grody website.
So, I'm going back to my original plan which is having all of my friends from Paris contact friends, family, ward members, and the institute president for available rooms or shared apartments.
Ew!! Need I say it again? Lesson Learned : If it seems too good to be true, it probably is.
Oh, and I also sent the creepy guy and e-mail telling him he was busted. :) Ick.
