i agree with flowers on the mantle & maybe a couple of candles, lit of course for the photo op. try the draping of a chenille fringed throw for the bench along with maybe an open hardcover old book turned over, like someone is holding the place in the book while they went to get a glass of something. definately try to take the photo from a rather non traditional perspective. experiment with some different angles , you might t be surprised with how things end up. definately need a bedskirt of some type, for that finishing touch look. i, personally, like to double up contrasting bedskirts for a tiered effect.
just my personal opinion, by all means each individual needs to go with the flow they are comfortable with & what they feel is appropriate for their B&B..
