First and foremost, ask yourself if it's your size and is it the bike you want? Then, assess the condition (it looks like it has new tires and tape, meaning that it might be currently in good running condition). Will you need to immediately sink more money into it?
Hard to say without more info. or better photos but, based on what we know, $100-150 seems fair (unless it's in like-new condition, which is highly unlikely). Italian equipped celeste Bianchis of comparabe age can be found on Ebay for $200-250, if you're patien. They may not be much better than that one, but they will hold their value much more.
