I've never used AirBnb. However, when making online purchases (even for physical items) I don't have a lot of trust. Many systems (reviews, ratings, etc) are all too easily exploited. While the thought of staying at a stylish house is more appealing than a room at a hotel chain, I at least know what I am getting myself into. I've had my share of... not great rooms at hotels, but they typically make it right with a room switch or reimbursement. It doesn't sound like AirBnb is good at that.
