I agree with Sky 100%.
What I have seen Airbnb do in the past is to give hosts one thing, but at the same time take away something else. I'm assuming that they are trying to be "fair." But this is a young company, run by young people who's notion of fairness is limited by their lack of life experience. In many places in the US, landlords rule. This is unfortunate when you have a landlord who is unresponsive or takes advantage of you. On the other hand, the landlord makes the investment and has the most at stake.
Few people are doing Airbnb just for "the fun of it." It's a business and everything about it should be standardized. I think those of us who welcome people into our own homes, would prefer, fewer, nicer guests than risk our personal domecile to guests who have little regard for much time and $$ goes in to providing a quality atmosphere.
Also, as far as standardization goes, I get little to no help from Airbnb at night or on weekends, and I get completely conflicting stores about Airbnb's policies. If someone is breaking a house rule there should be no question about taking a firm stand about it. Yes, as one person said, it will sour the relationship with this guest. But is this guest's opinion more important than your rights as a host? I think not.
If most hosts were more concerned about holding guests accountable, (as opposed to being worried about what guests have to say about us), then we could turn the tide of bad guest behavior. People coming to stay at an Airbnb, would know that policies are strict and would be enforced. They might not like it, but if they had to accept it, they would. Few people will turn down the opportunity to save a lot of $$ or stay in a unique location. Also Airbnb would realize a huge cost savings as they could employ far fewer people to listen to complaints.
