Thank you guys for your answers.
Peter G your comment from the estate agent I think is a bit of wishful thinking on their behalf ( I hope they are right ) because at the moment the 90 day rule is currently the full visa rule as far as I understand so I see no reason why it would be relaxed for us Brits if the ETIAS system is introduced.
Anne H , I never fail to have a wonderful stay in such a beautiful place.
I just pray that all this Brexit nonsense does not spoil things for the future.
I will stop there before I get too wound up about everything that is wrong with Brexit.
Thanks again folks.
