Question: what is the difference between guest house and b&b?
Answer: The size of the establishment As a broad rule of thumb, though, B&Bs tend to be smaller – most being under 10 rooms or so, and guest houses larger (often roughly 10-25 rooms). None of those dividing lines are exact though – and you will find 15-room B&Bs and eight-room guest houses (and indeed 'hotels').
