Born and raised here. It's a great city. Just be careful of certain neighborhoods on the south-side or on the west side. That's where a lot of criminal activity happens although there are bad people everywhere. Those are the areas you might want to avoid as the are typically gang infested.. Be careful taking the trains too with valuables and electronics. Be mindful of your surroundings. The best neighborhoods in my opinion are Lakeview, Boystown ( it's the "LGBT tourist attraction of the city) Logan Square, Wicker Park, Melrose Park, Oak Park, Hyde Park and of course the Gold Coast, Loop area or Magnificent Mile in downtown Chicago. Nothing more beautiful and breathtaking than the magnificent mile in the summertime or Millennium Park (another huge tourist attraction).
