Finding empty streets to take photos can be challenging and your post shows the best times to do so without people ruining the shot, that black and white night photo is great and makes the empty street a little eerie but in a good way. Sometimes I go out early in the morning for a walk and when I see a good moment I take some photos with my phone taking advantage of the fact that there are no people on the street, almost like the perfect set, those old medieval villages you mention are perfect for this kind of photography because the old stone streets with no one walking around make for better photos than trying to Photoshop out 50 tourists 😅
