I've been since 2011, this was by far the worst accommodation I have come across:
1) Three beds, all of which had unidentifiable/questionable stains on them
2) Two of the three beds appeared to have been slept in recently (bottom sheet was bunched up in the middle where presumably someone was sleeping).
3) Bed linens & pillow cases were low quality, mix and match
4) The fridge had dirt and grime in it, quite apparent it hadn't be cleaned recently
5) Toilets were far from clean - we found black public hair behind the seat
6) Shower & bath were not clean - more hair & dirt/grime
7) The dryer was on when we arrived - opened it to find it stuffed with someone's personal effects
8) The top drawer (chest of drawers) had multiple pairs of women's underwear
9) When we booked, the host said he would follow-up with check-in details as we got closer to the date. He didn't. I had to reach out to him our route hoping that he would respond with code, etc. Giving him 2/5 stars because he did respond when I reached out
10) Host did not show professionalism in his written communication, lots if "they day u leave", "treat the house like ur own" - when I saw this my intuition told me we might now be dealing with a professional with high standards.
11) Did not provide any toilet paper
12) Only source of heating was in the living room - the bedrooms were ice cold
13) The property was poorly lit, we had a hard time identifying it
14) The house and furnishings were dated, felt like college student rental property
It wasn't the case of the cleaner not showing up - the stains, dirt and grime were set and had been there for quite some time.
I expect the host is going to try to minimize my issues, but know that I provided supporting photos/evidence to Airbnb support and they instantly recognized that the host had violated the terms for Housing Commitment Standard Policy, immediately refunded us our money, and said that the host would be penalized for this fiasco. In other words, Airbnb looked at this situation and sided with me, not the host.
As an aside, AirBnb issued the cancellation ~8pm on a Sun. Property is in a sleepy little town and there were not other options for accommodation (no reception agent from any of the motels nearby were picking up the phone). We had to drive quite some time to get lodging for the night. My youngest daughter (11) was in tears at the prospect of having to sleep in one of his dirty, recently slept in beds.
