At the risk of being the mean voice here - I am assuming from your post that your landlord never knew you were hosting guests through Airbnb - and when they did find out they asked you to stop?
If that was the case - it was SO irresponsible of you and your partner to set up a listing. Airbnb make it very clear in their conditions that you must make sure that your property, and the local town/city/county, have authorized you to rent out a space.
I have never seen a residential rental contract (the lease you signed with your landlord) that allows additional paying guests or permission to sub-let WITHOUT the express written permission of the owner. There are all sorts of legal issues that could result - including a guest who refuses to leave and ends up with housing rights, someone injuring themselves as your guest and wanting to claim on a public liability policy, extensive accidental/deliberate damage to the property that needs insurance compensation being disallowed because you were not legally permitted to have guests. Although these things are rare occurances, they do happen, and you have lost the backing of Airbnb because you had no valid permissions in the first place - therefore you would personally become liable.
So there shouldn't be any extenuating circumstances here. You will be fined and your guests, and/or Airbnb, will have to find alternative accomodation which is not only disruptive for them as travelers, but a bad mark against Airbnb as the booking company.
So best advice - delist your property immediately, and cancel your profile if you do not want to pay the fines you should pay as it is unlikely Airbnb would chase you down for them - often they just add them to your account to be taken from future booking fees.
Sorry to be the voice of doom. And apologies if you did indeed have written permission from your landlord and they have just decided to take that permission away. Oh, and your landlord will also be responsible for the State sales tax, and local occupancy tax applicable for the guests that have stayed with you since the beginning of your listing - so make sure you give them all the details and your gross earnings for 2016 and 2017.
Wouldn't it be nice if it was all just as simple as taking money from some nice people who stayed for a while in your spare room. Unfortunately it's not.
Best Wishes.
