I just come back from a two weeks holiday in Bali. I travelled all over the island with my two years old daughter and my husband. We had a great driver who took us across the island and showed us its wonders. His name is Ketut Sukadana, his mobile from Bali 081 236 32166, phone 0361 294193, balimahiholiday@hotmail.com. The price was 30 euros for a day.
I warmly recommend him, he is nice and trustful. He speaks english.
