Most people here will tell you to just call it as it is, and they are right you can't really dress up a rough neighbourhood but Assata, if you want to have a go at it, you could try from one of two way.
If you are a host speaking of your own property in the listing description...
"The neighbourhood has a rather eclectic feel to it!"
I love that word, Eclectic is a great word, it covers a multitude of sins!
"The neighbourhood is possibly a bit left of centre!"
Meaning all is not what it may seem!
"You will adore the complex mix of society here"
And if you are speaking as a guest leaving a review.......
"Every neighbourhood has it's character, this one maybe a bit more than most!"
" Charm and sophistication are something that escaped this part of town"
And if you want to get your point across a bit more bluntly, how about one of these.
"Your vehicle may be best left in a secure parking station!"
???????
"A $10 note wouldn't last long on the ground in this neighbourhood!"
"You would want to keep a tight grip on your purse/wallet in this part of town!"
There should be something there for any scenario!
Cheers.......Rob
