I lived in Hartford for about 15 years before moving to Massachusetts. It has crime just like all cities. I walked around but I was armed. Downtown during the day is normally good though there has been some increase in crime downtown according to a small business owner I know downtown. Just be aware of your surroundings and you should be good. Living there I saw alot of crime , drugs , homeless but I wasn’t in the greatest part of Hartford. Trouble is definitely there just don’t go looking for it. I worked and lived in the city , and saw a lot. Not trying to scare you. Stay safe. Good luck. I feel bad for the homeless but drugs are usually a factor and mental illness. I always gave them a bottle of water.
