This is one of my primary grievances with being an Airbnb host. We are held accountable for declining too many requests, yet the guests are not held accountable for the way in which they make their requests. I clearly state that I will not accept reservation requests that do not include some sort of introduction, etc. This is my home and NOT a hotel. If they do not take the time to read my requirements before requesting to stay it makes me feel as though they may not follow my house rules, etc.
I feel that Airbnb should put some level of accountability on to the guests regarding this. There should be a form they fill out for the request indicating number of guests, length of stay, purpose of visit (vacation or work), and a brief one to two sentence introduction. This should be mandatory. If we decline we are expected to explain why. yet, the guests are not expected to offer any information when making requests. I beleive in communication, but I firmly beleive that the accountability factor must go both ways.
If I quit being a host, this will be the reason why. I am tired of the "hotel like" mentality with which guests are increasinly being encouraged to view our services when we open our HOMES to them.
