Practical, nimble, and fun to drive. For rather small drivers up to 1.75 m there's plenty of space even on the back seat. Useful driver-assist systems, and Android Auto works well. Very economical in summer. In winter a lot of energy is used in the first five minutes to bring the battery up to 20°C, which makes consumption on short winter trips very high.
