The mane Katz museum is a relatively small museum - a 4 room appartement... It hosts changing themes. We've just been to see the 'desire for Paris' exhibition - didit on Saturday, at noon, when you get a complimentary commentary / guided tour of the exhibition. The guide (Lilia) was very knowledgable, and we enjoyed the visit.
Of course you need to check what will be on display before you go, as it will change (3-4 times a year).
