Made is very reliable when it comes to transportation to/from airport and hotels. However with tours, I'd recommend planning out exactly what you want to do with him in advance. My mistake for not realizing this and completely trusted the tour descriptions on his website, which turned out to not be very accurate. For example, we just finished the central mountain tour with him, and we did not go to the monkey forest, instead TWO shopping destinations were added to the itinerary, where he let the shop guides take us and waited for us in the car. Waste of first few hours of the tour.
