The gas station is good, but the staff, accordingly, does not know Russian and it was also very difficult to speak English. We rented a car, but we didn't know what kind of gasoline to fill up with)) but with the help of gestures, they figured it out, refueled, the tankers did well.
There are no problems with refueling, they can wash the windows while refueling for free, they are mostly clean anyway. We do not wash them, they are always dirty.
