We just got back from POR last week and as far as location goes, I would recommend Magnolia Terrace. Close to the bridge by the main pool, quiet pool and laundry are close, close to food court, and bus stop.
Just a warning though, our housekeeping was definitely not up to disney standards, actually, it was borderline awful. We didn't do too much complaining while we were there because 1.) we didn't want to waste any more time during our vacation complaining and 2.) we had to do a lot of fighting to get the location we did in the first place so we really didn't want to lose the room location (we needed connecting rooms for twelve nights close to everything because mom has a bad leg).
But, as far as location goes, Magnolia Terrace was definitely great!
