Re Graham's remark about Quay House, I did indeed stay there for the Falmouth Raid (of happy memory) last September. It was exceptional, not least because John Carty, my host, was such an interesting person, and the view down Mylor Creek was fabulous, especially bird-wise as the tide came in.
UNFORTUNATELY, I'm pretty sure it is non-available (as sort of confirmed by the blank screen if you try the link). One of the amazing things about John Carty was that I discovered (and could scarcely believe) that he was well over 80 (AND, unbelievably because of how mobile he was, had two 'tin' knees). At the time I stayed, the house had been sold, and Mr and Mrs Carty were looking to retirement to another smaller house in Mylor Bridge. So Quay House can be left off the list - sadly.
