Firstly,I`d like to say thank you for sharing your experience like this way because your story give me a lot about insight how guest see listing.I can see a lot to learn from it and it help me to learn guest behavior and standard.
You haven`t describe detail of situation under how your booking made other than it was your daughter did it,so I just comment what I think with some assumption(correct me if it was wrong)
I got a impression you(or your daughter) made booking just before your trip schedule,maybe a week or so?If so,you better think about reason why dates are available.It could be because that room is not so popular,or could be too expensive.
Normally "good" listing is very quick to be sold away early such as 3-6 weeks.
Golden week is very popular and busy season.If dates are available even last minute and rate are cheap(no idea how much you paid although),you better wonder why.
Picking up listing from host with many listing is also bad sign because I am sure host must outsource cleaning task to cleaning company.I do not say all of them are bad on quality but it is very likely host did not check in detail.
Listing you should have look for is,
-Super Host with less than 3 listing.
-Whole one house,not apartment room
-price is more than average(higher price mean you got better chance to have better service and quality)
-Calendar date looks busy up to two month away.
Risky choice you are likely to be not satisfied with,
-Host with many listing like more than 10
-Price is lower than average.
-Calendar date looks empty even at busy season.
