The Art Nouveau Museum is generally interesting, but quite small. It is a large apartment with an interior of the early 20th century. At the same time, attendants in appropriate costumes also play certain roles: the girl at the piano, the cook in the maid's room.
Also in the basement there are several halls dedicated to architecture and household items of that time with interactive screens for additional information.
Admission costs 5 euros, which is quite a lot for such a small museum.
