@Mark116 I don't think it is a bad thing to host long-term guests at all. It is what I have been doing for some time and I have to say, although there are the occasional problems (nothing drastic though), percentage wise, you get more problems with short term guets.
However, you cannot rely on Airbnb to supply all the relevant information for each locality. It is up to the host to research that. I know that by law, my long-term guests absolutely cannot claim any tenants' rights and neither could long-term lodgers, because that's not possible under UK law.
We all need to get versed in the laws that apply to our areas and make judgements based on those. Airbnb isn't going to do that for us, just like they don't advise us on tax regulations in our individual countries.
