The departure stop did not match the address given on the booking confirmation by 1 kilometer. That is why we almost did not get our bus. There was no way to contact the company by phone. We were lucky that the departure time was also wrong. But that can also go quite badly! The exit stop was also several kilometers away from the specified coordinates. We where to be in Istanbul at 6 a.m. but we arrived at 3a.m. and had to sit at the street until it became light.
