I'm not a fan of pool views in general, as they tend to be noisier - however, the quiet pool views at Boardwalk are really not bad at all - if you can get on one of the wings, you get a partial pool view combined with a view of either DHS or Swan/Dolphin and the river and boats going by. The end rooms in the wings are particularly nice, as you get a nice, large balcony plus a side window over the river...4095 is a favorite room of mine with the two way views:
Also, though it's a farther walk from the lobby area, the little garden down at the end of the Boardwalk villas, facing Swan and Dolphin, is a lovely view - quiet, a little park and garden, and higher floors get lovely views of the boats, river, and Swan and Dolphin at night. Plus, that little back door is a convenient place to head in and out for walking to the Beach, Yacht, Swan, and Dolphin, or catching the boat to DHS or Epcot from the Swan/Dolphin dock, which is right across the bridge. Here's a view from 5027:
Even the lower floors that sit on that little park have a lovely expanse of greenery, with the Swan/Dolphin in the distance - this is from room 2010:
