I would keep your sun room light and airy and open. Put some sheer curtains on the windows and put up some pictures of the ocean! Don't fill it with too much furniture either. I would suggest a chez lounge and a cute little side table with a lamp. Put it in the middle of the room. Then use this room to relax in with a book or a magazine and a drink at the end of the day! One day I will have a room just like this!
