Airbnb is a home sharing platform. It is based on TRUST and Economics. It is equivalent to staying at your friend's house and leaving them some money to pay for the associated costs.
I have to trust that you will respect myself and my home. It is not a hotel, motel, nor even a bed and breakfast. I want you to be happy so if you are used to a hotel experience please book elsewhere, my place does not have those standards of service. It's a simple home intended for nice people on limited budgets.
