It's usually not crowded, though that is not always a bad thing. You can see paintings and early sketches from Gounaropoulos. But, it should be mentioned that the museum also hosts paintings, items and sculptures from other artists and even kids. Opposite of the entrance of the museum there is the house of the artist aformentioned; it is unique and bizare in a good way.There I also a small park outside where you can sit. It is not a must, although if you happen to pass by, by any chance, it will worth your time.
