Daytime 08-18, Mon-Sat, there is no free parking in the city center marked by the blue and green zones on this map. Evenings, nights and Sundays are free.
Outside the city, there are usually no parking restrictions. As long as you don't disturb anyone (keeping a distance from populated buildings is always a good idea) and don't need any facilities like water or a toilet, there should be no problem to park a micro camper at most locations.
