@Gretta-and-Carl0 I would ignore it if you are the freeholder. I assume it is a covenant but who does said covenant benefit? If you don't know the answer to this then it is unlikely that the person benefiting from the covenant knows either!
I trust you are aware of the Furnished Holiday Let tax rules, the requirements regarding number of nights booked for business rated properties and the capital gains tax implications.
If you have a mortgage you need their permission to rent short term and finally I hope you have proper insurance covering short term rentals.
