What to ask, and why
Will I have to block extra nights on the calendar?
Sometimes one. It depends on the odor and the treatment; ask the provider directly whether your current gap is enough.
Should I photograph the unit before treatment?
Yes. Date-stamped photos and the invoice are what a booking platform will want if you file a claim against the guest.
Will my next guest smell a cover-up?
Not if the source is treated and no fragrance is added. Ask whether any scented product will be used.
A guest set off bear spray. Is my unit usable?
After residue is removed and the unit ventilated, yes. Soft goods that took a heavy dose may need replacement.
Do I have to be there?
Usually not. Access can often be arranged through you or your cleaner; agree on it in advance.
