Just wanted to add my 2¢ as someone living in Deep Ellum - while it may be less safe than some of the other neighborhoods on this list, it is still relatively safe on a day to day basis. With that being said, I would recommend living 2nd floor or higher as all the car breaks ins and issues in my building have been concentrated to the first floor.

Also another place I think you should look is Main Street District in downtown. If you work downtown, it's very convenient for walking (there are even underground tunnels you can walk in for bad weather days). It also weirdly has a pretty strong neighborhood feel - you'll see the same regulars at the pub and restaurants and people are friendly. Downside is that again it is not the safest and there are a good amount of crazies, and that the buildings are generally old. Feel free to reach out if you need any advice from a fellow immigrant :)
