We stayed there for 2 weeks in May, & just got back from another 2 weeks 11/7.
The resort rooms & hallways are definitely in need of a refurb (mostly minor such as chipped paint, slightly stained carpet, loose knobs, slip & slide sofa cushions, etc), but we didn't encounter any major issues or dirtiness.
The lobby as usual, was stunning.
The resort is still our favorite for fantastic views, walking/boat to 2 parks, Skyliner nearby, great Community Hall, attentive staff, interior corridors, & having so much to do at night.
Btw, were you thinking of WLing a Standard View Studio or 1-bdrm? If a Studio, your chances are poor & you would be better off trying for a Garden/Pool View. BWV SV Studios are one of the hardest WDW reservations to get, even at 11 months (only AKV Jambo Club & Value are more difficult).
