Just a heads up as a lot of people get confused with Cranagh, the room number e.g. B4-5, means you're in Block B, Flat 4, Room 5. There are five or six flats in nearly every block and five rooms in most flats so someone who is in B3-5 is in the same block as you but a different flat and someone who is in is B4-2 is in the same block and flat as you. Hopefully that makes working out who your flatmates are a bit easier!
