At this point is a metal gate across the street. When I arrived, it was open. In the evening a man came and said that the road - starting from this gate - belongs to his property (the house at the end of the road).
He wanted me to pay 3€/300 ALL for parking with the car [there was no sign on the gate or whatsoever]. I'm not sure what is the best type to add this information, maybe mark the road as private, or add a "paid parking along the street" etc. After the gate is room for two cars, but there are no official parking lots.
