You have to buzz in the door with a code, but once you do, you are in a beautiful authentic Art Nouveau interior. The staircase up into the rest of the building is worth popping inside for in its self! The staff are very helpful and friendly and dressed in period costume, which was fun. There are cards about the rooms in several languages but one of the guides gave us extra information and directed our attention to features we may have missed. We were given period hats to wear while we walked around - a bit unusual but amusing. I found the kitchen especially interesting with cookies on offer! The attendants really knew their stuff and could answer our questions and give interesting facts.
A thoroughly interesting little gem of a museum - not expensive to enter, either.
