As someone who has lived in the Heights for 20 years, it's very chill here. not a ton of bars or anything fun really, but not super far from downtown where there is a ton of food/drink/etc. We have never felt anxious around here and I used to work super late and come home walking by myself at 2-3am routinely with 20lbs of camera gear in my bag and thankfully it's been incident free. I don't do the late nights in recent years, and use Uber a lot more... but overall we are pretty damn content here and were lucky enough to find our most recent rental, and the owner lives next door so we don't have any challenges dealing with absentee landlords etc.
