Minecraft wiki entry for Tips_and_tricks, associated text: If you decide on a nearby spawn base, the first priority is safety—pick an area that is well lit and closed off from dangerous areas, and specially protected from creepers (stone/cobblestone walls, a door, and glassed or fenced windows to view the area in front of the entrance). A small room will do, but there needs to be enough space for a crafting table, a furnace, and at least one double-chest to store supplies (these can be embedded in the floor if needed.) Of course, you also need space for the bed, and free space next to the head of the bed to respawn. There should also be room for an infinite water source, which can be tucked half under a wall.
