We saw some cops guarding the entrance to the street where the house was. We came and asked them if we could go closer and they wanted to see our ID. We didn't have our passports on us but I had my Czech ID card. They called someone with my name and date of birth and then allowed us to enter the street. It was really weird as they never asked for my husband's ID. Despite not sure they would have been happy with and Aussie driving licence hahaha. We came quite close to the house, but it was still behind a fence. I believe it is open sometimes and one can take a tour, but don't know what days.
