This museum is dedicated to the life and times of the Polish-born Frederic Chopin. It's got a lot of material in it about Chopin, but a lot of it also seems to be about a lot of the other people in his life. While that's to be expected to a certain extent, it seems that it's only about 50% Chopin and 50% everybody else.
The museum is laid out so that you start out on the ground floor, then go down one level, and then go up to the floor above ground, and then the floor above that. It's a little strange.
The exhibits themselves are not well laid out either. The items are all numbered, but the numbers are not in order! To confound things further, the item descriptions, which are also numbered, are also .... not in order. This leads to a difficult examination of the material because you have to figure out what number item you're looking at in the first place, which might be a bit more obvious were it in the order you'd expect numerically, and then you have to hunt for the corresponding number in the item descriptions. After all that, you've likely lost your place with the item you were looking at to begin with, and have lost interest by trying too much to struggle to find anything in the display.
There are music stations on the ground floor, but on the lower floor, there are sets of headphones and a confusing display based on a book with blank pages that gets its content from overhead projectors. I couldn't figure out at first how to get anything to play, and half the headphones were in mono (one ear was not working). This is in a place that's supposed to be celebrating the music!
There was a non-working "Musical Twister" on the second floor, which we really wanted to show our young son, but couldn't. Only one of the note "pads" did anything when we stepped on it.
The top floor, which gives the story of the end of Chopin's life, is a room with REALLY tall exhibits in it, crowded in a rectangle, which you can walk around in on the inside or on the outside. It is a strange way to lay out an exhibit, because it towers about twelve feet high, but of course only six feet or so are used for the actual content (which is again poorly laid out and has a confusing interface). It's just awkward, like someone saw that the high ceilings were there and they decided that they MUST spend the budget to get as close to the ceiling as possible.
A numer of the displays on all floors were closed for technical issues.
The highlight of the museum was the modern art exhibit of people creating works around Chopin, an exhibit the quirky greeter suggested we would either absolutely love or hate depending on "whether we liked that sort of thing" with respect to modern art, making clear his preference against modern art.
The coat check was staffed on our arrival, but when I went to get my coat, there was no one there (good thing I had no valuables in it) and so I just went behind the counter and got my own coat.
The store across the way is a decent museum store but is not actually connected to the museum.
