I love it here at GW. If you choose to attend, I doubt you will be disappointed (unless you just don't like law school which is a different situation entirely).
I commute from Virginia (Rosslyn) and I think it is perfect. It takes me 15-20 to walk including the 2 minutes I am on the metro. Living on or around campus is rather expensive and you can have some run-ins with the undergrads, which are doing what undergrads do . . . Rosslyn is nice because it is quiet at night.
I never even think about the Gtown students enough for them to make me feel inferior, which they wouldn't anyway. I actually don't think I have even run into any but I probably wouldn't know if I had. GW has a strong alumni base doing some really great things so I feel GW students have just as much of an advantage as our friends at Gtown.
All the faculty have been great. My fellow classmates have been nice, I haven't run into jerks which is a plus. My over all experience has been great.
Good luck on your decision making process and congrats on getting into GW!
