"I was looking to book two single rooms for my daughter and I, and I got some strange prices, to put it that way," he said.
"Two single rooms, mid-week, in July, for my daughter and I, and the price that came up was â¬4,110."
Duffy added that breakfast was included in the price but that dinner was not, and added that both hotels were five-star establishments.
"In fairness, I hadn't intended booking in that hotel, but it was through Booking.com, you know when you put in a town and a lot of different hotels will come up," he continued.
