Google maps broken for some Seattle addresses

Google maps shows incorrect locations for some addresses in the Queen
Anne neighborhood in Seattle, displaying them as Downtown locations.

Try, for example, "705 2nd Ave W, Seattle, WA" in both Google maps and
then Mapquest (the latter gets it right). Google appears to be ignoring
the directional after the street name. Doesn't matter if I spell it out
"West" or abbreviate it "W", it gets ignored by Google.

I'm not completely surprised about this, Seattle addresses are
something of a mess; the city has eleven different street addressing
systems in use. Still, it should do the right thing.
