I noticed as you went further east it became less glamourous (for want of a better word).
Oh, you have no idea. Actually it's the west part that gets dodgy. From West to East, it goes Airport -> Downtown -> Ward -> Waikiki -> Diamond Head -> $$ Kahala $$ -> Hawaii Kai. We used to joke that my boss never made it on the other side of the airport, and I don't think he ever did in 5 years.
I recall a stabbing which lead to murder in the middle of the day downtown once. A helicopter chace another time... etc. etc. But, what do you expect when 50% of the people loitering around down there look like the rejected extras from Breaking Bad.
The beaches though, rocked. I jogged at Ala Moana a few times a week, swam there a few times a week. Very nice, very quiet. Got a lot of thinking done. Enough that made me realize I need grid lock in my life.
