The guests must leave the house in the same condition it was in when they arrived. Therefore, the guests are responsible for cleaning the house at the end of their stay.
However, some hosts prefer to use a cleaning service that will also take care of the cleaning after the exchange.
For this reason, it is important to discuss how the cleaning will be handled in your conversation before the pre-approval or finalization of the exchange. It is better to be clear about whether the host uses cleaning service (has a housekeeper that will do it) or whether the guest will be responsible.
If the host charges a cleaning fee, the amount should be reasonable and the guests have to be informed BEFORE the exchange is pre-approved or finalized. Any cleaning fee must be stated in the home description of the host and discussed in the conversation beforehand.
