Well,,,, I'm not sure about the rent price. I believe it is a historical site now.. It dates back to Pre, WW2 when many poor folks live in what was referred to as Ghettos.
If I was in Warsaw,, I would defiantly like to visit it. I do like HISTORY related things.
Here is something interesting for you to visit.
I can also direct you to some incredible YouTube cooking/baking category sites. You don't need to speak the lick to understand what they are making.:drool:drool:drool
