This historical house offered promise of an interesting slice of life in World War II, but was pretty much ruined by the tour guide. She was completely "over the top" on the religious aspects of it--to the point of really warping the history. I think references to the Christian beliefs of the Ten Boom family are completely appropriate, but this should be an historical tour, not a hellfire-and-brimstone sermon.
The other objection we had was that it was way too long. The excessive length was caused by the inappropriate sermonizing about Christianity.
I read some other TripAdvisor reviews, and it seems like our experience was not necessarily the case for other visitors. It just depends who your guide turns out to be.
