I've stayed there and as was said above, it is "unique".
Nice place though!
It can be loud, especially if you're getting in bed before the last of a wedding crew gets tucked in.
Either stay up and be the loud one getting in late/early, be mentally lubricated so you don't hear anything, or bring a fan/sleep machine to drown it out. Worse on the 1st floor of course.
Lighting in most rooms leaves a little to be desired (understandable in the context of a restored old church) so if your wife/GF/hooker will care about that while getting ready, be prepared with a lighted makeup mirror.
That was the only issue I heard out of my crew.
Rooms are not cookie cutter so you may have a structural beam in the middle of or weirdly shaped oblong room, but in understanding what it is and why you're there that shouldn't be an issue.
It's certainly got charm and the appeal of something historic that was preserved.
If the wedding is there (they have a chapel / reception area and do lots of weddings) then it is definitely advantageous to be there. Might be harder to justify if the wedding is elsewhere.
It's neither the Ritz nor a Hampton Inn, but it isn't supposed to be.
The Who Dat Cafe is a few feet away and is a great spot for breakfast and to watch some of the local characters.
We've done a second line from there to Frenchmen and it was, er..um.... interesting.
