I spent four days at POP last May (did a split stay at POP and BWV) and fell in love with it. I was in the 50's building, only a minute or two from Everything POP on the very end, next to the stairwell. It was so quiet I never heard a soul while I was there (and I am a very light sleeper). I liked it so much that when I took my son and D-I-L in Sept we stayed at POP (instead of POFQ, where we had originally planned). They too loved it. We were on the back of the 70's building, third floor facing the lake and again never heard a peep from anyone. Very quiet! I've received towel animals both times I've stayed at POP. It's the only resort I have received towel animals at (not WL, AKL, or BWV).
I'm taking my mom to WDW Dec 9th-18th and we're doing a split stay at POFQ and CSR, but I'm taking my 9 y/o GD back to WDW Jan 2nd-8th and we'll be at POP for some GM-GD time. Can't wait!
If you're concerned about noise take a white noise machine with you. It will lull you to sleep, plus you won't hear any outside noises. POP is just so cute!
