I clean the space myself. I clean it as if I were using the bathroom or sleeping in the bed. Other host might charge you a cleaning fee and hire an individual to clean. If it's not cleaned to my standards, then it's not ready for my guest. Paying others to do what one feels a guest deserves is not hosting; it simply just flipping for the next guest.
