Useally you need permission of the landlord to sublet or to host paying guests (Airbnb)
Also be aware most landlords do not want to accept risks related to hosting guests.
Also consider how taxes, local laws, insurrance are involved.
If there are no extra costs for the landlord (higher energybills, taxes etc...) and you have permission, then 40% of earnings going to the landlord seems very high to me (?)
