I'm a 33 year old Director of Developer Experience for a small startup in Seattle, WA. I've stayed a number of AirBNB locations and I love getting to meet new people and experience the "real" side of the city. I stay with AirBNB hosts because I like being able to feel at "home" while I'm on the road.
I'm pretty quiet and casual, you probably won't even notice I'm there. Unless you provoke me, at which point you're likely to have a great time. :)
