If you are going on your own what do you plan to do or see when you are there (walking, swimming, beaches, shopping, castles, historic houses or what?).
If you can give us an idea what you like we may be able to suggest a good place to base yourself.
Are you going by car, train or what?
Trip advisor is a good site to get specific informaiton about an area.
