B&B means Bed & Breakfast
Or the Dutch translation: Bed and breakfast. It is a place to stay (often a private house) where you can spend a short time and where you can enjoy breakfast. The term B&B is known for in the United Kingdom, but it is also becoming more and more famous outside. In The Netherlands It is also called bed and breakfast, but then it is more of a hotel room, which does not fit completely with the original B&B.
