Hi @Joe4584 .... you have a lot of great responses so will keep this brief.
I agree with not using any synthetic fragrances. We always take out the plug-in diffusers and 'reed' smelly things we find in homes we stay in. Plus, I do not want to smell 'Himalayan jasmine' while I am staying at an Airbnb in Canada. Or 'English rose & cedarwood' while I'm staying at an Airbnb in the Med.
For my own STR property in Australia I have timber bedside tables, a timber dining table, a timber dining cabinet and timber office table. Between guests I use a lemon & eucalyptus oil infused wood polish on the timber items. Eucalyptus being native to Australia. It leaves a beautiful light 'real' lemon woody smell that is delightful.
Hope that helps 🙂
