The regulations aren't guests responsibility the hosts and airbnb should be compliant.
AirBnB and competitors are very important despite their flaws. Standard rentals are too inflexible for long term (month long) travellers and the hotel industry is either too expensive or not designed for long term stays.
As a digital nomad, I've had my share of bad accommodation (and really really good ones as well). Usually I just write them off and leave early, or identify stuff within the first day, that's very important. If you think you're going to be unhappy with the product you have to back out quickly.
False information or problems at the start of the accommodation, like broken items, are a deal breaker. This has been quite rare, and it might be the hundreds and hundreds of nights of stays but the two times I've had to contact AirBnB support it's gone in my favour (that's not to minimise the experience of the OP).
More often the bad experiences with AirBnBs are more subtle. Items that are just not comfortable or kitchens that don't really have what you need to cook.
Of the 65 hosts I've stayed with, 2 were bad enough to leave (as mentioned), and probably 2-3 more were the suffer through variety. That's not a bad percentage really.
