Quick answer: A fragrance free formula that comes in a refillable pump bottle made of cloudy plastic. Bonus: if it is made with organic sustainable materials.
Why should I use a fragrance-free soap and shampoo for my VRBO?
It is the option that will appeal to the most guests. Adding fragrances to soaps and shampoos requires ingredients which will increase the chances of a negative (or allergic) reaction. Plus what smells good is completely subjective. You might love the smell of lilac but some guests are going to find it disgusting. So play it safe and go with fragrance-free because there is no upside to having a fragrance but there is plenty of downsides.
Why should the soap and shampoo for my VRBO come in a refillable bottle?
Because it will cost less money. Buying a new bottle every time is unnecessary and will become expensive. Go with a brand that comes in a nice bottle that you can put out for guests and has a larger gallon size bottle you can buy at a discount to refill from.
Why should the soap and shampoo for my VRBO come in a pump bottle?
A pump bottle helps prevent overuse and is more sanitary. The pump bottle prevents random pieces of whatnot from getting into the bottle. And it controls the amount that comes out so guests do not accidentally dump the entire bottle out when they use it.
Why do I want a cloudy plastic bottle?
It will look cleaner and save you time when cleaning. Cloudy plastic hides soap scum and water spots that are otherwise a pain to remove. Plus, cloudy plastic doesn't let guests know how much soap is left in the bottle because they always look full. And since full bottles look better than half full ones, it looks better to guests. But refilling bottles after every guest is a tedious task. Select a cloudy plastic to make the bottles look uniform and full for each guest.
Do sustainable organic products actually matter?
For some guests, it is the difference between booking with you or someplace else. This is certainly not true for most guests, but if having organic products in your listing gets you a handful more bookings a year then it will more than pay for itself. While it might not be necessary, they can be a nice bonus that helps improve your bottom line.
