Don´t get misleaded. This awesome museum is not exclusively about cerámicas. You can find all sorts of ancient artifacts of the traditional Valencian Bourgeoisie. The building alone (Palacio del Marqués de dos Aguas) is wothwhile a visit. The late Baroque and Rococo palace has so many items to explore.
My two favorites are the old kitchen on the 2nd floor and the XXL chaise-longue for a real great siesta.
This wonderful museum is located down town in the palace of the Marqués de dos aguas; Calle Poeta Querol 2
