You need not fret in Cordoba. It is generally peaceful and safe, there are no violent criminals, just mostly bag snatchers and pickpockets.
Some safety tips:
If you ever become a victim, call the police immediately. If you intend to make an insurance claim, your insurance company will require a police report.
Cordoba has a very good health care system. The Pharmacies, which can be known by the large green cross outside the shop, are open 24 hours. Medicine, depending on the type, may be dispensed without a prescription.
The water is generally safe to drink but to be on the safe side, drink bottled water.
For tourists from other EU countries, don’t forget to bring your EU health card. You can use this to cover medical expenses.
