BWV's are definately not "nice".
nice would be just about anywhere other than the BW (& SSR)
BW on the other hand, is
absolutely AMAZING!!!
stunning lobby, incredible views, walk or ferry to EPCOT/MGM, great night life, delicious baked goods/paninis at the bakery (ohhh, & the smell wafting from it

), quiet strolls around the resort, surry bikes........
we've really haven't had probs with worn/dirty rooms (some minor stuff, but nothing that couldn't be/wasn't fixed quickly).
btw, before buying
DVC, we would walk along the BW, looking at the balconies, slightly envious of the ppl lucky enough to be staying there, awakening to the most incredible views in WDW (this even tho we stayed at most of the deluxes, concierge, as well as mods).
even after years of living my "BWV dream", i still get that shortness of breath & awe as we pull up, & that constant feeling of amazement just staying there.
yeah, i think you'll love it!!
