Weclome to forum, @AlexandCharlie !
You’ve done a good job on your listing, IMO. One thing perhaps, is that it can be a little difficult to read for some, with long sentences and such. ChatGPT?
I think you are probably right, that it is a long time to plan ahead for a short sit. But not impossible to get applicants at this time, ofc.
Your target group for this sit would probably not be intl. travellers so much, but sitters going to the area anyway, filling a gap in their itinerary or visiting family/ friends in the area (or even a local sitter, looking for a change of scenery or vacating their own home for redecoration or to get some peace and quiet from roommates
).
Something I notice lacking (?) and that I know many sitters look for in a listing, is actual size of bed (as queen/ double and such vary in meaning in different countries, and many sitters value sleep..), where the pet sleeps (many sitters will avoid pet in bedroom/ bed) and how long the pet can be left for outings in the area (or even if there are pet-friendly cafes and such in the neighborhood if it can’t be left). It is good to have this in the listing, as I think sitters that look for these things would often scroll on rather than ask you if they don’t find the info.
Many sitters have an end cleaning routine, and might avoid shortish sits as it won’t be much time for leisure. An idea for this sit could be to mention that for this short sit the sitter can just tidy after themselves and strip the beds and you will take care of the rest. If you have a good sitter, you should find your home in a nice state regardless.
As it is December, you could consider to check whether there’s some nice Christmas events or sites those dates, and say something in the listing on that topic. Ofc if the pet permits the sitter leaving to visit such a site.
Don’t do anything or offer anything you are not comfortable with, and follow your gut if anything feels “off”. That being said, I think it looks lovely and could well apply if I was in the area. Best of luck!
