Google Stradomska 15, 31-068 Kraków, Poland. The pinball museum is tucked away down a little archway that has a sign for Atlantic Squash and Wellness above it. Through that archway it is tucked down to the left, down a small flight of stairs.

I hope you found it. Took us a little searching. Our hotel was walking distance to the place. I remember walking thru a short tunnel/alleyway and it wad on the left, below ground.

I confirm what peopel said above, it is not difficult to find on Google maps. Walk down the little alley and then you'll see the entrance. There is a flight of stairs going underground. It is fairly straightforward.

We used google maps, there is a big board on the pavement on the main road and then you need to go through the alleyway to the side of that and then left again down the steps. Hope you find it

I just used gooogle maps not hard to find walking distance of centre. View the entrance pic then you recocgnize it

Hey chip, I can help. Have you been to Kraków before?

It’s just past the castle on the left
