As a guest, I feel way more safe using Airbnb when I'm renting an extra room in the host's home. Even better if there are strict-sounding house rules. It makes me feel like I'm sharing a living space with a real person rather than helping somebody play landlord with their rental-only flat. And judging by the article, it's better for the hosts as well.

I've been living like this with different people for the past month or so. It's been about the same price as a hostel and so much more comfortable and interesting! It would be a shame if lack of trust brought prices up and made this way of life no longer viable.
