Great spots. Close to the old town. Don't park right on the right if it's raining, as there are lots of puddles. There's no lighting or curbing. We paid €12.60 for 24 hours.
Great place against the city wall.
Note 3 different parking zones and operators against each other. Respectively 25, 12 and 18 euros per day.
Place on the photos 18, along access road 12 and below 25 euros.
So pay close attention.
Not a particularly beautiful place, but it's a decent place to spend the night; it was quiet at night. Close to the old town with the Alexander Nevski Cathedral, the short walk is worth it!
