I agree with Michael K's review - the less you know about the Bayernhof Museum before visiting, the better!!
For me, Bayernhof Museum was a random google find that intrigued me. Calling the museum a "music museum" is really unfortunate though. It is so much more than a collection of music boxes! The tour guide was fantastic, while the tour itself was quite quirky, especially as it continued and neared the end.
My husband said he enjoyed this home tour more than Fallingwater, and I have to agree. No, the Bayernhof has nothing to do with mid-century design, but as far as pure entertainment value goes, it's top-notch!
