Green Gables B*B - Great views; nice place; if you enjoy walking you can enjoy a nice walk by the ocean to the aquarium and bck.
If you want something lower priced but with a nice view of the ocean Monterey Beach Resort - Best Western has easy access to a stroll at the beach (romantic for location - but there are nicer places with nicer rooms.)
In addition to Green Gables, also look at the Martine Inn in P.G.
