Conference room
From Tardis Wiki, the free Doctor Who reference
Ianto Jones planned to have a nap in the Hub's conference room, but was unable to when Jack Harkness gave him work to do. (AUDIO: "Incubation: Know")
Jack turned the conference room into a private sauna by pumping steam into it. St John Colchester restored it to its proper function. It had leather seats. (AUDIO: The Empty Hand)
