I have been to Moraitika and Kassiopi , love the restaurants in Kassiopi, and Virginias cocktail bar😉. The north is lovely but for the last couple of years we have stayed in the south, very different, quieter and the restaurants are cheaper. The coastline is stunning, I was lucky enough last year to see dolphins just outside of Beniteses.
I have not been to the British War Graves garden Pennyfarthing, so will pay a visit. There is a Monty Don programme Friday 7pm, he visits Corfu and gardens there so it may come up. It is called Monty Dons Adriatic Gardens.
