It was wonderful to stay at William's. I'm not a diligent traveler and the only thing I did before my arrival at Hilo was book a B&B so had no idea to do at Hilo area. He brought me every information I should do to fully enjoy Hilo area. It was truly helpful and the restaurants he recommended were all good(he really is a gourmet!).
The conversation while breakfast was joyful too!
Just a thing I'd like to add is - if you are not a dog person, you might be scared by big dogs there.
