I've had wonderful experiences with AirBnB! This seems like a really great community of friendly travelers that are happy to share their local wisdom and homes.
I've been fortunate to have lived on both coasts of the USA, lived a little over a year in Santiago, Chile as an undergrad, and spent time abroad in Costa Rica, Mexico, England, Canada, and traveling throughout South and North America. I love traveling and wish I could do it more often, though I do adore the Seattle area I call home. It's awesome not only because of good people and good food, but the access to swimming, hiking, biking, camping, sledding and so many other activities WA has to offer.
Safe & fun travels, all!
