I've bounced around from apartment to apartment the past few years. I used to go for a ground floor apartment but got too tired of hearing noises above me - especially when the upstairs neighbor works night shifts and vacuums their floor at 3am. Needless to say in my current place I requested to be on the top floor. I'm also pretty lucky that none of my neighbors currently have dogs or kids. I hear one of my neighbors from time to time when he's drunk and has company over but it isn't that often. My advice - if you don't mind climbing a few flights of stairs go for top floor.
Make no mistake - apartment living is never as nice as house living but when you're single it does offer you some freedom to pursue other things than cutting grass and home repair.
I've also had better luck with the more "upscale" places than the lower income places. I've lived in enough lower income apartments to write a book - loud love making, weed smoke, drunk neighbors, fighting, police visits, etc. No thanks. Once I earned a bit more money and elected to go to a nicer apartment complex I've had much better experience with the neighbors and higher quality conditions.
Go top floor - for your own sanity.
