I would keep your valuables locked up and/or out of sight. Beyond that; if you discard any notions of partying with the "locals" soaking up a bit of local colour, a romantic dalliance or 3, or wandering around looking like a convenient and easy mark I'd be shocked if you had any trouble. You'll likely come away thinking that its a quiet and friendly place.
On the other hand, if you went out inviting trouble it would be rather easy to get into some.
