Wow! This is a gem. I'm so glad I read the reviews before visiting Amsterdam and decided to visit Our Lord in the Attic. First, it's a great chance to see the inside of an old canal house and get some sense of how the people lived in the 1600's. Second, the house and the church have a great story and give you a good sense of this aspect of Amsterdam history. The church built across the attics of three canal houses is amazing, and very well-preserved. The self-guided tour is very informative, engaging, and easy to use. As other reviewers have said, the stairs are steep and narrow, and might be very difficult for the elderly.
