Advice needed from Seattle members

I have a opportunity at work to transfer to Seattle WA and was looking for some advice from members in or around the Seattle area. I will be working in downtown Seattle near Quest stadium (Seahawks). I have heard the traffic can be bad, but probably not as bad as here in DC area. Any recommendations on neighborhoods to look in or to avoid ? Kids are grown so no need to worry about school districts etc. Any help, ideas or info would be appreciated. Will be in Seattle approx. 3 weeks from now, for 2 weeks of work and recon. Thanks.........Kevin
