Is cleaning the property upon leaving necessary?
This will vary from property to property. In some cases the owner/manager will have a cleaning crew come in after you leave, although you will most likely be expected to leave the property as tidy as possible so the cleaning team does not have to deal with any major messes. In other cases, you might be expected to clean the property (washing linens, dishes, etc.) before leaving. Be sure to check with the owner/manager on their check-out policies.
