Rostov is pretty safe in daylight, and in the dark I guess too, but it is better to have a pepper spray in case of emergency. And I wouldn’t recommend you clubbing alone. Clubbing here is not popular and you can find only shady men

A fairly safe city, except for the conflict between Russia and Ukraine Because of the political conflict, drones fly in the city and sometimes they blow up houses, but explosions happen rarely Also, because of the conflict, mobile Internet is often disconnected

It is calm enough here, you can walk with a phone or other valuable things during the day. However, it is better not to leave them unattended. It is safe at night, but it is advisable not to walk around unfamiliar dark courtyards. Passers-by will always help if necessary, tell you something. People are mostly kind among strangers, especially if strangers are initially kind to them. Police are almost always ready to help, but they may not come to a call for small hooliganism (or come in a few hours).
