Do not use completely generic names such as "Parking" or "Public Parking" for anonymous parking facilities. If a Parking Lot has no specific name, leave the name field empty, but don't forget to set the street and city fields. This should be the road where the (main) entrance of the parking lot is. This way when you search for a parking in the app you can see the difference between the Parking Lots and it won't fill the map with unnecessary names.
