Here's info about Turkish visas for US Citizens (assuming that's what you are):

Actually, even if you're not a US citizen you can get visa information on the same site.

Whether or not you want to go there in the current political climate is up to you. If it were me, I'd take advantage of the opportunity, but everyone has a different comfort level.

Whatever you do, enjoy your trip!
