The majority of the lower class workers of the Titanic (i.e. stokers, firemen) slept in the front of the ship under the forward deck. Stewards and maids slept on C-Deck, and the officers slept on the top deck in the "Officer's Quarters", which was right under the first funnel. There were also sporadic crew cabins throughout the ship, most of the time near the part of the ship they worked in most.
