I am very sorry that you did not enjoy your tour. It was very unfortunate that your regular guide was tested positive at the last minute and I needed a quick replacement, not one from my staff. He told me that he took you to the Wannsee Villa. I am not sure if you are aware of the fact that outside guides are not allowed to guide in there. So all he could do is point to the things worth seeing. Please feel free to contact me directly to discuss this further and please be assured that we strive to offer only excellent tours.
