Haunted house in Gdansk - what is the exact address?

I am going to go to Poland, Gdansk and just thought to find something abandoned and interesting. So I googled it and found that there is an abandoned manor, but I failed to find any coordinates of this place. So maybe someone can help me find it?

The story is here: The Haunted Manor in Gdansk, Northern Poland.

And more concrete information with address is here O nie-masońskiej kamienicy przy ulicy Sobótki; Google translate: About a non-Masonic house on Sobotki Street

Maybe someone knows where it this on Google Maps? I tried a couple of adresses, but no luck.
