I rented a No Smoking apartment but somebody in building Smokes

[John-Oliver0]

It is advertised as NO SMOKING. That's why I rented it for 6 weeks. But someone in the building smokes all night and the smoke keeps me up and I cannot get any sleep. The renter has offerred a refund for the remaining days of our contract, but it's not so easy to just up and run. There are expenses and schedules to keep and not the best availability in my area. Is there some kind of option I can use to get the full refund for my stay. What is the policy regarding hosts who cannot or will not enforce the no smoking policy. Seems like falso advertising if you say no smoking but then there is an overpowering smoke smell that prevents you from sleeping and working and enjoying your time,.
