Cara, as Brian said the stewards were quartered in the main accommodation area for victualling crew, on the port side of E deck in large dormitory-style rooms. You wouldn't find any stewardesses sleeping down there, though. They were provided with two or three berth cabins in various locations among the 1st and 2nd Class passenger cabins, often in spaces next to stairwells or toilets which wouldn't have been too popular with paying customers.
