The Viktor Kovačić Apartment Museum
Time Out says
Not just behind closed doors but also up the stairs and under the attic, this semi-precious stone of a museum offers a unique insight into the interior design world of pre-World War I Zagreb. Architect Viktor Kovačić designed this city-centre residential building in 1906, reserving the top floor flat for himself. Preserved in almost pristine original form, the flat is a treasure trove of period furniture, boldly patterned wallpaper and intelligently-designed domestic utensils. The fact that it is only open on Thursdays adds to the charm.
