Grzybowski home in Szpitalna Street 1. Open

I am helping my cousins trace their great great grandfather Adam Tomasz Grzybowski, who was baptised at St Mary’s, Krakow, on 11 Dec 1812.  The baptism record says he was born at the home of his parents Piotr Grzybowski and Anna Sobolewska, the previous day. It gives their address as “Szpitalna street no. 564” according to the translation I have. I looked at Google maps and found “Szpitalna street” but it doesn’t seem long enough to have a No. 564.  I wondered if anyone knew the area and could assist me with that. One cousin and I are in Australia. She is thinking that when she next visits her sister in Scotland they could go to Krakow to see where their ancestor was born and baptised. Adam did a medical degree in Berlin and was a surgeon in Edinburgh and London. He married their great great grandmother in Edinburgh in 1834.
