I studied abroad in Budapest this past year and was fortunate to travel to many European countries. I spent part of my Spring Break in Paris and enjoyed it. I stayed in the 12th arrondissement and felt relatively safe. I walked around a lot (Louvre, Eiffel Tower areas), even at night - but I remained vigilant at all times. I stayed in a shitty airbnb, but would recommend single or women-only hostel rooms if you are aiming for the most protection at night.
In all my travels, I've had the fortune of never being harassed, so I can't speak much on that. I literally have a full can of mace that I've never used. I always walked around with my DSLR and a small backpack but made sure to keep them close and unsusceptible to theft. As a Black woman travelling in predominantly heterogeneous places, I experienced a lot of staring but that was it.
My biggest travel tip is to always download offline maps in Google Maps and Maps.me. If you don't have free data/wifi hotspot this saves the trouble of asking strangers for help or desperately trying to find wifi. This saved me a lot because I only had a Hungarian sim card and didn't want to rack up too many roaming charges. I also used Google Trips because they have a nice planning feature where you can map out your travels for the day.
France was definitely the most diverse place I visited, so I almost felt at home. I enjoyed Paris and would go again!
