We were lucky enough to have Kadek collect us from the airport as part of our villa transfer. He told us of a number of tours that he could offer us as our driver for the week.
During our week holiday we used Kadek and his company a number of times, he is a complete gentleman and represents the very best of Bali. Kadek seems to know something about everything in Bali and his English is fantastic, it was so informative learning from him about religion, culture, politics, how rice grows, the monkeys etc.
When Kadek wasn't available to drive us he always found us a friend or relative with a comfy car to take us to where we needed to be and his prices were very very reasonable. He offers tours around the most popular destinations but will also take you to anywhere in the island at your request. He's also very good at suggesting places to go and can cater to those who are looking for a Bali tourist holiday or those wanting to get off the beaten track.
If you're staying in Nusa Dua area I wouldn't think about using anyone else, 110% recommend.
