Bypass capacitors for STM32F0 series?

Hi.
I am designing a test board using STM32F0 series MCU.

On the datasheet, it states I have to attach 3 bypass capacitors(2 x 0.1uF, 1 x  4.7 uF) per each VDD. 

Is it absolutely necessary?, What is the point of using two identical capacitor, when I can use a single capacitor with about 0.2uF value? so that I only have to use 2 capacitors per each VDD pin saving me the board real-estate?

Anyone have ideas??

Thank you.
