@Wendy-and-Aaron0 uh, it happend to us ones , it took us 2 days to vent the place, after that we put new house rule "it is forbidden to cook smelly spicy food, fry fish etc.. " but our average stay is just 2 days and we are in the city center so our guests usually don't cook but eat in restaurants instead, there are plenty of them everywhere on walking distance.
If it happens often I would remove the beautifull retro stove and lave them just a small cook top with 2 burners and microvawe. Or just a microvawe and watercooker, toaster... you know, like a kitchenette. And I would remove this cool woman power poster 😄 and replace it with a picture of a sexy woman enjoying on the beach 😄 just to remain them they are on holliday , you know... feng shui hehe
We leave them a lot of leaflets of restaurants of all kinds (vegan, chinese etc...) , we allways recommend them some nice ones with croatian food, we also have plenty of city guides, a list of all events and festivals in the area etc... so they are to busy to cook 🙂 Try to do the same it is cheaper then plasma air cleaner which someone suggested 😄
