I just returned from Bali & used a great driver based around Sanur but we've he will take you all over the Island. His name is Budi, he's a safe driver, reliable & he has a well maintained Toyota Vios which is basically the same configuration / size as a Bali taxi - only unmarked. You can call him on +62 812 360 5998 or 081 236 05998 or ask for him at the Sanur Beach Hotel.
