I found Anguk's contact in TripAdvisor and decided to contact him given the good price for transfer from Ubud to Dempasar Airport (highway route, much quicker) for 300,000idr. Very quick reply via WhatsApp. And finally someone with excellent English! It was refreshing to be able to ask questions about the culture in Bali and get very detailed responses... Basiclly a tour guide! Recommend as a driver and we are a guessing also very good for day tours.
