I'm a 29 year old artist from Australia, planning my first trip through the US & another through Europe in May/June '13. Yay!
I'm a painter/illustrator, with work online (i'll send you the URL if you're interested - Airbnb blocks the address in my profile!)
Did my first trip through Europe last year with airbnb and it was rad. London/Paris/Barcelona/Berlin then back to Perth. Barcelona was my stand out. Beautiful and just ALIVE. :D
I've been share-housing since I was 18 with friends and strangers alike, so I'm used to living in (and respecting!) shared spaces.
