I stayed in a B&B once for a romantic weekend away with an open-plan loo.
Obvs the photos in the listing just showed the lovely roll top bath in the bedroom, NOT the loo completely exposed on the opposite wall...
Needless to say it was not romantic in the slightest :(
It had recently been refurbed and refitted, all very lovely and expensive. Tons of floor space. No reason on god's earth why they couldn't have stuck the loo in a little room with a door...
I think it must be a fetish thing.
