@Chelle83, understandable that this is stressful.
There appears a steady trickle of THS Forum posts by pet parents that struggle to find hosuesitters. Sometimes this seems to reflect macro trends (e.g. non-US sitters avoiding US listings); sometimes new THS policies (e.g. booking fee impact on short duration sits); sometimes (and quite often) reflects frankly unattractive listings.
We guess - perhaps wrong - that a good portion of challenges are mirrored on other platforms. But sometimes the only way forwards is to experiment.
In meantime, suggest take a critical eye to your listing. Review other listings in your area. Ensure photos look attractive (no clutter) and cover all key areas of property. Ensure amenities completed. Add information about local travel facilities (airports, train, bus). Add info about local attractions. Consider sweeting listing (e.g. add use of car, permit early arrival/late departure).
