Duvet - down or synthetic?

[Fairisle0]

Hi all, planning to be a host on Airbnb and wondered which type of Duvet is best? I am in Scotland so it will never be tropical !
I have seen lots of information on bedding but nothing on the actual type of duvet. 
Thank you for any replies and advice.

Hi @Fairisle0 

Welcome to the community 😊

Aside from looking nice, duvet  cover protects your comforter and helps keep you warm and comfortable through the night.

Best Overall:

Brooklinen Classic Duvet Cover at Brooklinen- reasonably priced, considering its hotel-quality appeal.

Best Budget:

Quince Organic Luxe Waffle Duvet Cover at Onequince.com- Handmade in India of 100-percent organic cotton

And, 

Coyuchi Organic Percale Duvet Cover at Coyuchi.com- low price but high quality

My flavor is the Ralph Lauren Spencer Border Duvet Cover at Macy's of the Best Cotton Dovet Cover

Ralph Lauren cover has a clean-cut, sophisticated vibe. Love it.

Happy Hosting ✌️

@Fairisle0 And now to try to answer your question: We have gone for non-allergenic 13.5 tog duvets. Better quality certainly exists but a) They would be feather/down and hence allergies are a concern and b) Our apartments are well heated so a 15 tog is not needed.
