Hello Max -
We stayed at T.Mill last year, oddly enough having checked it out from a visit to Merrose Farm. Anyway - you will not be dis-appointed with the setting, peace & quiet, helpfullness of the owners, location and just about anything else.
We love the Roseland Peninsula and would always go back to T.Mill if returning to the area. We found that using the King Harry Ferry, on a weekly ticket, is a much better way to get across the Fal rather than using the road around it. Saves alot of time - queues were sometimes a nuisance but never as long as the road around via Tregony.
Best wishes,
Chris & Sue Kelly
