In 230 V territory that wasn't all that uncommon back in the day, at least for smaller apartments. Houses had up to three fuses. I distinctly remember seeing pictures from a Munich apartment built some time between 1965 and 1973 (major changes of regs., 1965 saw the new wire colours and 1973 the ban of TN-C final circuits), with a 24-space distribution board populated with one lonely 16 amp MCB. Hot water and heat were presumably central, cooking most likely gas. Dishwashers weren't really a thing back then and washing machines had barely started to become popular so in reality 3500 W was reasonable for a 1-BR.
Once I even saw the meter setup from a rural cottage presumably first wired for electricity in the 1940s or early 50s. The meter has a maximum current of 10 amps at 220 V and there was one single 6 amp circuit (fused neutral).
