Translation of empedernir

I arrived there but could not find a hotel immediately, so that I took my luggage with me. I know that this is very provocative to thiefs. One should not walk on the street with a big backpack.
The view from the top was awesome. From there one could see that every house almost had a different color, but that the roofs were all tiled. I took my camera and took several images on diapositive.
San Telmo and Bocca were two additional neighborhoods that we have visited and these were actually quite nice. We were warned by the staff of our hotel to be alert in these neighborhoods as there were many thieves.
