Where do you suggest to park car in old town area or nearby?
Is it hard to find a parking spot in old town area? How much does it costs?
There is a decent parking lot right under the old iron bridge (next to the Bulwar hotel). Or you may try your luck finding a parking place at one of the streets in the Old Town, try to enter the Old Town from the east, ie from the area of the Toruń Miasto railway station.
In any case finding a parking place is not a big challenge in Toruń.
