We booked Eko after reading about him on Tripadvisor, and corresponding with him via email, and we would highly recommend him, (and we are seasoned travellers and quite particular). We are two parents with a teenage daughter, and travelled with him for three days in December. He really understood what we wanted to do, and travelled at our pace and time, and was flexible as to the plans. His English is very strong, so no problems communicating. Very polite and very nice. Just having conversations with him, helped us learn so much about what what we were seeing, the culture and the people, which was important to us and truly enhanced the experience. He also seemed to really enjoy hearing about our lives. He suggested that instead of just taking a boat from Sengigi to Gili Air as a means of transportation, that we use the time in the boat to visit Gili T and do some snorkelling, so as to get a "two for one deal" which was economical financially and time wise. I wouldn't hesitate to recommend him to anyone, as you will be in good hands. The only thing I would inform people is that the driving can be a bit long, - 2 hours in each direction depending where you are going, which is just the way it is, so good to ask about this, and be prepared. Not a problem if you take some snacks, and just keep on talking. Our holiday was just lovely, and we would be pleased to respond to any questions.
