It's usually better to write about somewhere you know well, because your familiarity with it will make it far more interesting than an attempt to write realistically about somewhere you've never been. After all, a place that seems mundane to you because you're so familiar with it may seem new and exciting to your readers if they've never been there, and you don't have to risk the people who have been there thinking it sounds fake. Actually, I'm writing a story set in and around my hometown, and even though it's very boring to me because I've lived here for most of my life (not to mention it's where I went to high school, which can sometimes make people resent places), I'm starting to appreciate it more because I'm looking at it from the perspective of someone trying to capture its essence in writing, or from the perspective of my characters who recently moved here. I'm not suggesting that you set it extremely close to where you live, but as long as you have both a good personal familiarity with a place and an ability to see it from the eyes of the characters, I'd be fine with any setting.
