Yes, it is generally safe to travel in Europe. I have travelled extensively both on my own and with a partner and personally find Europe to be very safe. I find countries in the Balkans and the Nordic countries somewhat safer than Western Europe, but I consider no European country unsafe. However, as with travelling to any foreign country, it is important to be aware of your surroundings and take the usual precautions for personal safety, such as keeping an eye on your valuables and being cautious in crowded areas.
