I haven't actually.
I wanted to but my then-fiance-now-wife thought Karlovy Vary would be more interesting which led us to end up going to Prague with a side trip to Karlovy Vary. We still hope to get there though.
When you go, perhaps you would take a small donation and some pics to the baby house number 1 for me?
Got an 11 year old daughter who was living there at age 3 before we brought her home.
