This week's competition begins at the Inn Castledawson in County Derry-Londonderry, where the tranquil river views go down a storm, as does an afternoon boat trip.
Married couple Des and Mandy host the week's second visit, at their Drumrush B&B in County Fermanagh. The B&Bers embrace some inner peace with the stunning views and an afternoon of Pilates.
The third visit of the week is to County Antrim, where June and Stevie host at Ballylough House. The cleanliness standards immediately get a dusting down, but spirits are stoked by a visit to the world-famous Bushmills whiskey distillery.
Neil and Rush host the week's final visit at The Wylies B&B in Lisburn, Northern Ireland. The B&Bers feel pampered by the sleek, luxurious interiors and superb spa facilities and the hosts even offer their guests a pillow menu to ensure they have a great night's sleep.
It's payment day and the B&Bers finally find out what they've been paid and who's won - but not before they've bickered about breakfasts, scolded each other's scores and clashed over cleanliness.
