Tenant compensation for paint inconvenience?

Hi, my tenants would like to be compensated for two weeks motel accommodation (totalling $870) as they felt they could not live in the rental property due to the bathroom being repainted (oil based paint). The tenants have stated that the smell was unbearable and has caused them medical issues which required x-rays. The tenants did not mention the two weeks accommodation until after the fact. There was also no effort to ventilate and they refused to leave the bathroom window open ajar as it was too cold and they felt unsafe doing so. The bathroom door can be shut preventing the cold air from reaching the bedroom or lounge and the window is not able to be completely opened preventing anyone from entering (unless they forced entry). The painters confirmed the smell would only last a few days with proper ventilation. I would like to know where I stand as the landlord? Am I required to compensate them? I feel this amount is excessive as two weeks rent for my property only totals $690.
