I approached Arie upon a tricky situation in which i was stranded in Surabaya airport but wasn't allowed to stay the night due to the airport's policy. He gracefully offered to put me up for the night and dropped me off at the airport the next day. Not only was this a massive act of generosity he explained to me his local culture and gave me an incite to some of the tours he runs to Mount Bromo for example , which I had already done but with a different travel company ... which is regrettable to say because the detail Arie explained to me about his personal tours sounded a much more thorough experience than the one I received booking in Jogjakarta. Although my story is not one experiencing Arie as a tour guide my short experience with him as a person, I could happily reccommend he would make a good tour guide and his office was located to the right of the exit if you fly into Surabaya airport.
