A modern gas station, a large parking lot, a clean toilet, there is a wheel pump, a cafe, payment in both dollars and Turkish lira, there are no free bars, as it were!
On a trip to Turkey, I refueled only at the gas stations of this network. There are no questions about gasoline. The gas stations are equipped with everything necessary, the staff works quickly, clearly, the language barrier does not interfere. I've stayed overnight a couple of times, the staff doesn't mind.
