To the right of the inn is the Flotsam guard house. The main point of interest here, besides vast amounts of loot, is a couple of training dummies upstairs. You can knock these down to help qualify Geralt for the Experienced attribute. You need to be quick about knocking these over, though, as seeing you with your sword out is going to make the guards nearby hostile. You can reset their hostility by taking a few swings, sheathing your sword, and then taking a few more.
