Which B&B for 1 night stay?

My husband & I are spending next weekend at JMU with some friends. We've decided to fly in to Dulles on Thursday to have a night on our own - it's been a hectic summer! We love B&B's so I've been looking at a number of them. The ones that look intriguing are Stone Manor, Welbourne Farm, Silverbrook Farm, Zion Springs or L'Auberge Provencal (which just may be much too expensive & formal!). We like comfortable & lovely, but we're 'jeans' kind of people. Any good last minute suggestions?
