My wife and I recently returned from our honeymoon in Bali. We used the recommendations from this forum to find a driver while we were there and called Putu.
He was excellent! I would highly recommend him to anyone who is traveling to Bali in the future. He is very kind and is obviously proud of his country. We both enjoyed our day with him.
He charged us 250,000 for the whole day but we paid him 350,000. Seems like a very fair price. He is most certainly worth it.
Here is his web site: http://www.arjunachariots.com
Tell him Tim and Carrie from America say "hello!"
