Excellent car for both city driving and long haul. Best mileage of ANY hybrid on the road, handles very well, super easy to park and has plenty of get up and go. If you're considering the purchase of a Prius C I'd highly recommend you take it for a few days and use it to run errands, get to know the car and see if it will suit all your needs.
Fits five adults comfortably and the trunk space is good for 98% of what I need it for. Sometimes you just need a truck, and a truck the C is not. But it's a fantastic little car.
Expect 55-65mpg, depending on your driving habits. If you're a pro or a hypermiler, you can get 78-85mpg in the right conditions!! Unreal!!
