Had a good and bad experience at the The Gallery B&B in Port Isaac.
The rooms were great and are certainly more contemporary than most B&Bs. The breakfast was good too.
However, on the second night the owner decided to have a party which lasted until well past midnight. I did complain at the time and managed to get the second night half price, but it did spoil our stay.
One note is that the parking is limited. It is okay to drop things off at the door, but the nearest parking is at the top of the village. However, if you know Port Isaac you will understand why!
