As no one's answered yet, I'll at least offer this. We stayed at Gillespie House ten years ago and had a nice time. I wouldn't call it exceptional or fancy, but the owners were nice, the breakfast was good, and the accommodations were more or less like staying in someone's old but well-kept house. Our suite had a nice size hot tub, which we appreciated. Oh, and the place was just off Main St.
Other than that, have you used this site?

You can at least narrow your choices down based on the things you want: full breakfast, spa tub, fireplace, age restriction, pets, price, etc. That should make it much easier to choose the place that works for you. Of course, I don't know if this site has ALL the B&Bs in F'burg, but it's a start.
