I am not surprised you are not getting any answers. This is your second post and the first while dismissing Letting Laws went out of its way to identify illegal lettings.
Anything Let over 31 days needs to be registered at the Town Hall and declared for Tax.
Tenants have far stronger rights than the UK. So you would be better off going to an Agent and make sure it is all legal.
Because you have highlighted yet another dimension that the authorities are looking into.
