Watch Four in a Bed online: Episode 7 Castle Hill Guesthouse, Lynton

It's Alistair and Emma Mundell's turn to host in sleepy Lynton, North Devon at their four-star premises which only opened three months ago. The B&B newbies are desperate to impress with their recently renovated rooms. The accommodation proves a winner with Mark and Fee and John and Neil, but Mrs Tee is proving more difficult to please. Later a ride on the Victorian cliff railway from Lynton to Lynmouth proves hard for two of their guests who are afraid of heights. Over dinner John and Neil reveal their B&B is in Blackpool - a town which which Alistair confesses is his `worst nightmare'. In the morning Mrs Tee says she didn't sleep because of traffic noise and is so critical of the cooked breakfast the other guests are reduced to hysterics.
