This is by far and away one of the most plesant B&B/Hotels I have sayed at in a long time.
Recently re-furbished, the decor and standards of finish are pretty amazing, rooms are a good size and the furnishings are of excellent quality.
The owner was warm and welcoming when we arrived and spent time giving us advice on the local restaurants, pubs and attractions.
Breakfasts were very good, with a wide choice of options, everything from a traditional English, American pancakes, kippers, kedgeree or continental.
Just be aware that is is awkward to get cars to the Hotel's carpark, but that is the nature of Penzance's super-narrow streets - nothing the Hotel can do about that. I got my mid-size SUV in there, just, but anything bigger and you'll get well and truly stuck.
Anyway, that is just nitpicking, I cannot recommend Camilla House highly enough.
